Reactions of 2-chloroacyltrimethylsilanes with Grignard reagents have been examined. Thus, treatment with methylmagnesium iodide affords the corresponding 3-(trimethylsilyl)-2- alkanones through an initial addition followed by removal of chloride anion and 1, 2- rearrangement of silyl group. In contrast, the reaction proceeds with 2 equiv of the Grignard reagents bearing β-hydrogen to give 2-(trimethylsilyl)-1-alkanols, where initial reduction of ...
