The hydrochloride was prepared by dilution of the reaction mixture with HCl (3 mmol) and water, which caused the product to precipitate. The mixture was heated to effect solution and allowed to cool slowly to crystallize the product. The crystals were collected by filtration, washed with water/MeOH, and dried under vacuum to give 106 mg of the title compound as a white solid: GC/EI-MS, m/z (rel. int.) 370 (M-15, 0.1), 265 (19), 264 (100), 163 (8), 121 (20), 114 (9), 91 (7), 71 (20), 70 (21), 58 (10), 57 (12).

In water; ethyl acetate; mineral oil; PREPARATIVE EXAMPLE 1 Glycidyl 4-t-butylphenyl ether A suspension was obtained by adding 50 ml of anhydrous dimethyl sulphoxide to 3.23 g (73.3 mmol) of sodium hydride (as a 55percent w/w suspension in mineral oil) which had been washed with dry hexane under a nitrogen atmosphere. 10.0 g (66.6 mmol) of 4-t-butylphenol was added slowly, dropwise, to the suspension, with ice cooling. After the 4-t-butylphenol had been added, the mixture was allowed to return to room temperature and was then stirred for one hour. 15.5 ml (200 mmol) of epichlorhydrin was added to the mixture, which was then stirred at 40°C for one hour. At the end of this time, 300 ml of water was added to the reaction mixture, which was then extracted three times, each time with 100 ml of ethyl acetate. The organic layers were combined, brought to neutrality with dilute aqueous hydrochloric acid, washed with a saturated aqueous sodium chloride solution, dried over anhydrous sodium sulphate and concentrated by evaporation under reduced pressure to afford an oil. The oil was purified by distillation under reduced pressure (140 150/2-2.5 mmHg) to obtain 13.3 g (yield: 96.9percent) of glycidyl 4-t-butylphenyl ether.

Following similar procedures to that of Preparative Example 1, but using appropriate starting materials, quantities and conditions, the compounds of Preparative Examples 2 to 7 were prepared.

YieldReaction ConditionsOperation in experiment
With water; cetyltrimethylammonim bromide; at 120℃; under 33753.4 Torr; for 7h;Autoclave; General procedure: The general process of CO2-PO coupling reaction was given as following: a 100 ml autoclave equipped with a mechanical stirrer was pre-dried under vacuum at 80 °C for 2 h. Zn?CoIII DMCC (10 mg) and appropriate amounts of quaternary ammonium salts were transferred into the autoclave, which was then dried for another 2 h. After the autoclave was cooled down to 25 °C, PO (30 ml) was injected into the autoclave using a syringe under negative pressure. The reactor was then heated and pressured to the desired temperature and CO2 pressure under vigorous stirring (500 rpm). After the reaction, the autoclave was cooled with ice-water bath and the pressure was vented. A small amount of sample was removed for 1H NMR measurement. The crude products were then transferred to a round-bottomed flask and dried under reduced pressure.

With C132H136Al2N4O5P4(4+)*4Cl(1-); tetrabutylammomium bromide; at 100℃; under 760.051 Torr; General procedure: The coupling reactions were carried out in 5 mL reaction vial equipped with a magnetic bar on an automated stirrer with heating mantle. The clean reaction vial was dried at 100 0C for1 h in an oven before use. The reaction vial was charged with appropriate amount of immobilized catalyst 1-Mont and co-catalyst and closed with septa. Next epoxide 2a-2i (10 mmol) was subjected to this vial using a hypodermic syringe followed by evacuation. Afterwards CO2 was introduced to thereaction vial at 1 atm pressure and the resulting suspension was allowed to stir at specified temperature for an appropriate time. The conversion and selectivity of the product was determined by 1H NMR of an aliquot taken from the reaction mass at a regular interval with respect to an internal standard.

On completion of the reaction, vis-cous liquid or solid product obtained was treated with methanol(2 × 3 mL) and centrifuged for the complete removal of organiccompounds from the solid catalyst. The evaporation of solvent fromthe combined organic layers furnished the crude product. A smallfraction of the crude product was directly injected to HPLC to findout the regioselectivity. The remaining portion of the crude mix-ture was purified by flash column chromatography (hexane/ethylacetate, 80:20) to get the major regioisomer in pure form. The puri-fied product was characterized by1H and13C NMR analysis. Theresidue thus obtained from centrifugation was dried in air (2 h) andthen at 200C for 3 h to get back the active catalyst (>97percent recovery)for the next catalytic run.
