Yield: 20 %Chromat.

Reaction Conditions:

with [Rh(OH)(cod)]2;1,2-bis((2S,5S)-2,5-di-i-propylphospholano)ethane in cyclohexene at 80; for 24 h;

Steps:

5
IN this example 5, phenyl,methyl,diethoxysilane of formulawas prepared as follows. In an oven-dried vial, [Rh(cod)(OH)]2 (4.6 mg, 0.01 mmol) and (S,S)-i-Pr-BPE (7.4 mg, 0.02 mmol) were placed. Benzene (1 ml), HMeSi(OEt)2 (134mg, 1 mmol) and cyclohexene (1.1 mmol) were added to the vial. The reaction mixture was allowed to stir for 24 hours at 80 00. GO-Ms analysis confirms formation ofPhMeSi(OEt)2 (GO-Ms yield: 20 %).
