diethyl trimethylsilyl phosphite

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To a mixture of diethyl phosphite (2.8 mL, 0.0217 mol) and triethylamine (9.mL, 0.065 mol, 3.0 equiv.) in dry diethyl ether (250 mL) at 0° C. was slowly added freshly distilled trimethylsilyl chloride (3.3 mL, 0.0260 mol, 1.2 equiv.) via syringe. The resulting slurry was allowed to slowly warm to room temperature, and was then warmed to 45° C. for 14 h. Volatiles were removed by distillation using a 55° C. oil bath. The resulting mixture was diluted with pentane (150 mL), filtered to remove triethylammonium salts, and concentrated at atmospheric pressure using a 55° C. oil bath. Distillation of the resulting oil gave diethyl trimethylsilyl phosphite as a colorless oil (3.64 g, 80%). was then warmed to 45° C. for 14 h Volatiles were removed by distillation using a 55° C. The resulting mixture was diluted with pentane (150 mL) filtered to remove triethylammonium salts concentrated at atmospheric pressure using a 55° C. Distillation of the resulting oil
