Metal–metal communication between 1,1′-bis(diphenylphosphino)cobaltocenium and an organonickel moiety

Abstract

1,1’-Bis(diphenylphosphino)cobaltocenium (dppc)+, similar to 1,1’-bis(diphenylphosphino)ferrocene, can be coordinated by dicarbonylnickel(0) or cyclopentadienylnickel(II), respectively. The cyclic voltammogram of [Ni(CO)2(dppc)]+ ([1]+) showed two reversible reductions, at potentails nearly identical to (dppc)+. The...
