Silyl-substituted alkylidenes: preparation of the novel complexes and mechanistic studies of their formation from reactions of alkylidenes with silanes and silyl-to-alkylidyne migration

The chemistry of the carbon–transition metal double and triple bond: annual survey covering the year 2002

“…Tantalum-carbene complexes were suggested as intermediates in the formation of -alkylidene-ditantalum complexes from alkylation of tantalacene dichlorides [456]. A single paper reporting on the synthesis of both silylcarbene-tantalum complexes and silylcarbyne-tungsten complexes appeared in 2002 [457]. Alkylidene complexes [e.g.…”
