The bond lengths in the carbyne complex [(CO)5CrCNEt2]BF4 suggest considerable participation of the resonance form (B). The complex is a valuable intermediate, for it affords carbene complexes even with weak nucleophiles. A new example of the utility of this approach is provided by the reaction of the intermediate with KAsPh2 to give (CO)5CrC(AsPh2)NEt2.
