Abstract

Pd-catalyzed C–H silylation reactions remain underdeveloped. General strategies usually rely on the use of complex bidentate directing groups. C,C-Palladacycles exhibit extremely high reactivity towards hexamethyldisilane and can be disilylated very efficiently. The C,C-palladacycles are prepared through halide-directed C–H activation. This account introduces Pd-catalyzed C–H silylation reactions with di­silanes as the silyl source, and is focused on studies on the silylation of C,C-palladacycles.
