Olefination and group transfer reactions of an electron deficient tantalum methylidene complex†
Abstract
The reactivity of an electronically unsaturated tantalum CH2 functionality are reported. Alkylidene 1 participates in group-transfer reactions not observed in sterically similar, but electronically saturated, analogues. Reactions with substrates containing unsaturated C–X (X = C, N, O) bonds yield [Ta]
