N-Heterocyclic Carbene Analogues of Nucleophilic Phosphinidene Transition Metal Complexes.

ABSTRACT: Chloride abstraction from the complexes [(η⁶ -p-cymene){(IDipp)P}MCl] (2 a, M=Ru; 2 b, M=Os) and [(η⁵ -C₅ Me₅ ){(IDipp)P}IrCl] (3 b, IDipp=1,3-bis(2,6-diisopropylphenyl)imidazolin-2-ylidene) with sodium tetrakis[3,5-bis(trifluoromethyl)phenyl]borate (NaBAr^F ) in the presence of trimethylphosphine (PMe₃ ), 1,3,4,5-tetramethylimidazolin-2-ylidene (^Me IMe) or carbon monoxide (CO) afforded the complexes [(η⁶ -p-cymene){(IDipp)P}M(PMe₃ )]BAr^F ] (4 a, M=Ru; 4 b, M=Os), [(η⁶ -p-cymene){(IDipp)P}Os(^Me IMe)]BAr^F ] (5) and [(η⁵ -C₅ Me₅ ){(IDipp)P}IrL][BAr^F ] (6, L=PMe₃ ; 7, L=^Me IMe; 8, L=CO).
