Getting up to speed: Both LiCl and the YCl3/MeLi catalyst system have an acceleration effect upon the substitution of silanesusingGrignardreagents (see scheme). The method provides access to benzyl‐, allyl‐, and arylsilanes in good yields from the starting silanes.

anionic strategies to construct silanes, the coupling of benzylic halides and arylhalosilanes with sonication has been identified as a high yielding and general strategy to access bulky and functionalized benzylic silanes. This new methodology provides a solution for the synthesis of families of bulky benzylic silanes for study in catalysis and other areas of chemical synthesis.
