Lewis basic saltspromote benzyltrimethylsilane coupling with (hetero)aryl nitriles, sulfones, and chlorides as a new route to 1,1-diarylalkanes. This method combines the substrate modularity and selectivity characteristic of cross-coupling with the practicality of a base-promoted protocol. In addition, a Lewis base strategy enables a complementary scope to existing methods, employs stable and easily
efficient procedure has been developed for the synthesis of organogermanium compounds and styrenes para-substituted with groups containing an atom of the 14th group by one-pot reaction of halogenosilanes, germanes or stannanes, organic halides and magnesium using ultrasound methods.

To synthesize 4B-group element-containing styrene monomers, alkylmetalation reactions of 4-methylstyrene (1) in the presence of lithium diisopropylamide (2) were investigated. Trialkylsilylation of 1 proceeded easily by the reaction with trialkylsilyl chloride in the presence of 2 to form mono- and bis-trialkylsilylated methylstyrene. This synthetic method was expanded to other 4B-element-containing styrenes such as germyl and stannyl compounds.
