A tantalum(V) carbene complex: Formation of a carbene-bis(phenoxide) ligand by sequential proton and hydride abstraction
Proton and subsequent hydride abstraction from the bis(phenoxide) ligand of the trimethyltantalum(V) complex affords a cationic tantalum(V) carbene complex, in which two phenoxide groups are linked to the carbene center. The electrophilic nature of the carbene functionality is demonstrated by the reaction with PPh3.
