---|---|---|
>= 99% | With [1,1'-bis(diphenylphosphino)ferrocene]dichloropalladium(II); copper (I) iodide; triethylamine; at 20℃;Inert atmosphere; | General procedure: A round-bottomed flask containing a magentic stirbar and iodobenzene (911.5 mg, 4.468 mmol,1.0 equiv) was added with PdCl2(PPh3)2 (62.9 mg, 0.0896 mmol, 0.02 equiv), CuI (34.9 mg, 0.183mmol, 0.04 equiv) and 5.0 mL of Et3N. The resulted mixture was thoroughly degassed by a steadystream of argon for 15 min before propargyl alcohol (0.14 mL, 270.2 mg, 4.820 mmol, 1.1 equiv)was added via syringe. Ther resulted reaction mixture was allowed to stir at room temperatureunder argon overnight. The reaction mixture was diluted with saturated aqueous NH4Cl and theseparated aqueous layer was extracted with 3xEtOAc. Combined organic phases were washed withsaturated aqueous NaCl, dried over anhydrous Na2SO4, filtered and concentrated in vacuo to givea crude material. The crude material was purified by SiO2 column chromatography eluting with10% EtOAc-hexane to give the desired product 1a as a brown oil (451.5 mg, 76%);. |

80% | (a) 1-(3-Chlorophenyl)-1-propyn-3-ol (yield 80% of theory), with use of 3-bromochlorobenzene. 1 H-NMR Spectrum, 100 MHz (CDCl3, TMS) δ in ppm: 2.2-2.4(s); 4.45(s); 7.2-7.5(m) in the ratio of 1:2:4. |
Yield | Reaction Conditions | Operation in experiment |
---|---|---|
77% | With hydrogenchloride; N-chloro-succinimide; In 1,4-dioxane; water monomer; at 20℃; for 5h; | General procedure: A solution of alkynol 1a (95.8 mg, 0.725 mmol, 1.0 equiv) in 3.6 mL of 1,4-dioxane was addedwith NCS (193.3 mg, 1.448 mmol, 2.0 equiv) and 1 M aqueous HCl (0.38 mL, 0.38 mmol, 0.5equiv). The resulted solution was allowed to stir at room temperature until the reaction was judgedcomplete by TLC (typically 5 h). Upon completion, the reaction mixture was diluted with water.The separated aqueous phase was extracted with 3xEtOAc. The combined organic phases werewashed with saturated aqueous NaCl, dried over anhydrous Na2SO4, filtered and concentrated toa crude material. The crude material was purified by SiO2 column chromatography eluting 10%EtOAc-hexane to give the corresponding 2,2-dichloroketone 2a-Cl as a yellow oil (117.2 mg,74%); |
