| 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. |
