## Abstract The deprotonation under basic conditions of the keto‐phosphane ligand in complexes {Ru(Cp)[η^1^‐__P__‐Ph~2~PCH~2~C(=O)__t__Bu](PPh~3~)(L)}[PF~6~] (L = CO or PMe~3~) that arise from the addition of L to {Ru(Cp)[η^2^‐__P__,__O__‐Ph~2~PCH~2~C(__t__Bu)=O](PPh~3~)}[PF~6~] generates {Ru^+^(Cp
