Lewis base-catalyzed perfluoroalkylation of carbonyl compounds and aldimines with (perfluoroalkyl)trimethylsilanes (TMSCF3, TMSC2F5, and TMSC3F7) is described. The nitrogen- or oxygen-containing an...
Irradiation of CF3-substituted benzene in the presence of hexamethyldisilane and octamethyltrisilane causes two types of photosilylation, namely one at a benzylic position to give the corresponding benzylic silanes, and the other at aromatic ring to afford the corresponding phenylsilanes.

Palladium-catalyzed coupling of arylhalides with aryldifluoromethyl trimethylsilanes is shown to form diaryl difluoromethanes. A simple dialkyl(dimethoxyphenyl)phosphine ligand for palladium, stabilizing π-interactions between palladium and the difluorobenzyl ligand during reductive elimination, and a cobalt-catalyzed synthesis of the silanes enabled the reaction to form diverse products, including
