In all cases the corresponding triarylmethylsilane was formed. The reaction of tri-p- chlorophenylsiane, tris-(p-tritluoromethylpheny1)-silane, tri-p-tolylsilane and tri-p- anisylsilane,~ 1 Ith methyllithium was investigated. Tri-o-tolylsilane reacts with phenylisopropylpotassium in a manner similar to tri-o-tolylmethane in that all three methyl groups are metalated. When the metalated product is carbonated, a silane tricarboxylic ...
