title: Deprotonation of coordinated phosphanes in a rhenium complex: C-C coupling with diimine coligands.
abstract: The reaction of fac-[Re(bipy)(CO)3(PMe3)][OTf] (bipy = 2,2'-bipyridine) with KN(SiMe3)2 affords two neutral products: cis,trans-[Re(bipy)(CO)2(CN)(PMe3)], and a thermally unstable compound, which features a new C-C bond between a P-bonded methylene group (from methyl group deprotonation) and the C6 position of bipy. The solid-state structures of more stable 1,2-bis[(2,6-diisopropylphenyl)imino]acenaphthene analogs, resulting from the deprotonation of PMe3, PPhMe2, and PPh2Me ligands, are determined by X-ray diffraction.
