Novel acyclic carbene-substituted phospha-palladacycles

Here, we report the synthesis of the first phospha-palladacycle substituted with an acyclic carbene. The reaction of bis(dialkyl)aminocarbenes with the very stable phospha-palladacycles leads to metastable η1-carbene complexes, which can be converted by intramolecular reduction to zero valent palladium complexes.
