Activation of A-H bonds (A = B, C, N, O, Si) by using monovalent phosphorus complexes [RP→M].
The available data on the activation of A-H sigma bonds by electrophilic terminal phosphinidene complexes are reviewed. Theoretical computations allow us to rationalize the experimental results. It appears that a successful insertion needs an initial interaction between the phosphinidene and the A-H bond, such as a donor-acceptor complex with a lone pair, a Coulombic interaction due to a negative charge on A or H, or a proximity effect.
