	With tin(IV) chloride In diethyl ether Heating;
42.6 %Chromat.	With allyl phenyl ether In toluene at 120℃; for 20h;	Hydrosilylation of allyl ethers General procedure: Hydrosilylation of allyl ethers was performed in ampoules at 80-120°. Weighed amount of the catalyst was charged into an ampoule, and a mixture of the siloxane, allyl ether, and toluene (molar ratio 6 : 4 : 1 was added); platinum concentration in the reaction mixture was 3×10-4-3×10-3 mol/L at Pt = 8×10-5 mol/g with respect to the carrier. Conversion and selectivity were determined by means of GLC (kinetic method) using toluene as interna l reference as described elsewhere [3].

55%	Stage #1: diphenylsilanediol With tris(pentafluorophenyl)borate In 5,5-dimethyl-1,3-cyclohexadiene at 40℃; Inert atmosphere; Stage #2: 1,3,3,5,5-hexamethyltrisiloxane In 5,5-dimethyl-1,3-cyclohexadiene at 40 - 60℃; for 2h; Inert atmosphere;	4 Example 4 Synthesis of 1,1-Diphenyl-3,3 ,5,5 ,7,7-hexamethylcyclotetrasiloxane (“Diphenyl-D4”) In a dry 250 L round bottom flask fitted with a magnetic stirrer, condenser, thermocouple probe with temperature control, heating mantle and nitrogen over-gas was placed 21.6 g (0.10 mole) DPSD and 40 g xylenes. The mixture was heated to 40° C. and stirred to partially dissolve the DPSD. Using a syringe, 0.2 ml of a 5% tris(pentafluorophenyl)boron in xylenes was added to yield a boron complex concentration of 100 ppm in the mixture. From an addition funnel was added 20.8 g (0.10 mole) 1,1,3,3,5,5-hexamethyltrisiloxane (M′DM′) at a rate that maintained a steady slow evolution of hydrogen gas. The addition continued for about 1 hour at 40-60° C. Upon complete addition of the M′DM′, the reaction mixture was stirred at 60° C. for 1 hour. When an FTIR analysis of the reaction mixture displayed no signal for SiH at ˜2150 cm-1, 0.2 g of magnesium oxide was added to neutralize the catalyst, and the reaction mixture was stirred for 30 minutes. The mixture was filtered into a 250 ml round bottom flask, and the solvent was removed using a rotary evaporator at 80° C. and <5 mmHg. A residue of 28.4 g was recovered that was 82% Diphenyl-D4 by GC analysis. A GPC analysis did not show the presence of polymer in the residue. The residue was flash distilled with a kugelrohr at 175° C. and 0.1 mmHg to give 23 g (55% yield) of 96.6% Diphenyl-D4 according to GC analysis.

Yield	Reaction Conditions	Operation in experiment
	With platinum⁽⁰⁾-2,4,6,8-tetramethyl-2,4,6,8-tetravinylcyclotetrasiloxane at 70 - 150℃; for 1.33333h;	54 (WARO 2598) is a laboratory prepared material obtained from the hydrosilylation reaction between MHDMH and an allyl started polyether with the formula of CH2CH-CH2-O-(CH2-CH2O)H with the allyl started polyether added in molar excess (30%) in the presence of the Karstedt PTS type catalyst. In a bottle with a magnetic stirrer, a dropping funnel and a refluxing condenser, flushed with nitrogen, 26.26 g of the allyl ether were mixed with 0.1 gram PTS (containing 1% Platinum) and the mixture was heated to 70° C. Then 13.4 g of MHDMH was added dropwise during 20 minutes. The system heated up by itself up to 150° C. during the hydrosilylation. The mixture was further stirred for 60 min at 140° C. and left for cooling down. The reaction product was predominantly Si-C linked as seen by NMR. The weight of the product obtained was 45.5 g. The equilibrate MHDMH was obtained as follows: 600 g of MHDMH were obtained from the equilibration of 1025g MHMH and 3800g of MHD2MH (see preparation in example 05) in the presence of 120 g Levatit K2641 (a sulphonic acid modified polystyrene ion exchanger available from Lanxess) under reflux for 3 hours (the temperature went up to 97° C.), and after cooling, the ion exchanger Levatit was filtrated through a folded paper filter with a pore size of 10 μm. The final product was distilled to get a product with 96% purity.

Yield	Reaction Conditions	Operation in experiment
56%	In ethylhexanol, 2- at 70 - 80℃; for 1.5h;	2 [Example 2] A 1 liter round-bottom separable flask with a 4-necked separable cover was fitted with a stirrer, a thermometer, a Graham condenser and a dropping funnel. The separable flask was then charged with 250.0 g (1.2 mols) of 1,1,3,3,5,5-hexamethyltrisiloxane, and the temperature was raised to 70°C. Once this temperature had been reached, 0.6 g of a 2% by mass 2-ethylhexanol solution of chloroplatinic acid was added, and the resulting mixture was stirred at 70°C for 30 minutes. Subsequently, 88.9 g (0.6 mol) of trimethoxyvinylsilane was added dropwise over a one hour period with the temperature held at 70 to 80°C, thereby initiating a reaction. Following completion of this dropwise addition, the reaction was continued with the temperature held at 70 to 80°C. During the reaction, the unreacted trimethoxyvinylsilane was refluxed. The progress of the reaction was tracked by gas chromatography, and the point where the chromatographic peak for trimethoxyvinylsilane disappeared was deemed to represent the completion of the reaction, and heating was stopped at this point. Following completion of the reaction, the interior of the separable flask was evacuated to a state of reduced pressure, and the residual 1,1,3,3,5,5-hexamethyltrisiloxane was removed, yielding a product solution. This solution was distilled, yielding 200.2 g (0.56 mol, yield: 56%) of the target product, 1-trimethoxysilylethyl-1,1,3,3,5,5-hexamethyltrisiloxane (13). [Show Image] The above compound was identified by 29Si-NMR and 1H-NMR. 29Si-NMR (C6D6): δ 8.33 to 7.82 ppm (CH2SiMe2O-), -7.23 to -7.51 ppm (HSiMe2O-), - 19.73 to -20.24 ppm (-OSiMe2O-), -42.56 to -42.97 ppm (Si(OMe)3); 1H-NMR (CDCl3): δ 4.70 to 4.66 ppm (m, 1H, HSi), 3.56 ppm (s, 9H, Si(OCH3)3), 1.09 to 0.56 ppm (m, 4H, Si(CH2)2Si), 0.17 to 0.02 ppm (m, 18H, Si(CH3)2O).

Amounts of the specific ingredients are set forth in Table 3 for Examples 3 a and 3b. The reaction was carried out in room temperature under nitrogen in a 10 ml thermostated reactor equipped with magnetic stirrer and a three way glass stopcock connected to a nitrogen gas circulating system fitted with bubbler. An amount of D3 was sublimed on a high vacuum line into the reactor which was then filled with nitrogen gas and an amount of HMMH, of ABCR(97%) purified by keeping EPO over fresh CaH2, dodecane and prepurified toluene were placed in the reactor by means of Hamilton syringes under positive pressure of nitrogen. An amount of the stock solution of the catalyst, B(C6Fs)3, in toluene was introduced by a precision Hamilton syringe. The time of the catalyst introduction was considered as the zero time of the reaction. Samples were withdrawn by means of Hamilton syringe and analyzed by gas chromatography (GC). Results for Examples 3a and 3b are found in Tables 4 and 5.

Yield	Reaction Conditions	Operation in experiment
84%	In toluene; xylene at 20℃; for 24h;	5 Example 5: Preparation of BoIa benzyl esterIn a round bottom flask, 3-allyloxy-3-benzyloxycarbonyl-pentanedioic acid dibenzyl ester (5.03 g, 10 mmol) in 25 mL of dry toluene was introduced, followed by 1,1,3,3,5,5-hexamethyltrisiloxane (4.38 g, 21 mmol) in dry toluene (10 mL). EPO Karstedt's platinum hydrosilylation catalyst, platinum-divinyltetramethyldisiloxane complex in xylenes solution (0.02 mL) was added and the mixture was stirred at room temperature in a dry atmosphere for 24 hours. The volatiles were then removed in vacuo without heating, and the residue was purified by chromatography over a silica gel column, eluting with hexanes/ethyl acetate (15: 1 to 4: 1) to afford 10.14 g (84%) of the title compound as a colorless viscous oil. 1H NMR (CDCl3, 200 MHz): δ -0.01 (s, 6H); 0.02 (s, 12H); 0.37 (m, 4H); 1.44 (m, 4H); 3.17 (dd, 8H, J1 = 15.7Hz, J2 = 32.2Hz); 3.33 (t, 4H, J=6.9Hz); 5.06 (s, 8H); 5.10 (s, 4H); 7.31 (br.s, 30H). 13C NMR (CDCl3, 200 MHz): δ 0.85; 2.07; 14.66; 24.31 ; 39.83; 67.18; 67.99; 68.13; 79.10; 128.96; 129.12; 129.25; 136.05; 136.34; 170.42; 171.19.
