Iridium complexes of perimidine-based N-heterocyclic carbene pincer ligands via aminal C–H activation

Hill, Anthony; Ma, Chenxi; McQueen, Caitlin; Ward, Jas


The reactions of N,N′-bis(phosphinomethyl)dihydroperimidine pro-ligands H2C(NCH2PR2)2C10H6-1,8 (R = Ph 1a, R = Cy 1b) with iridium(I) substrates have been investigated and shown to readily result in chelate-assisted C–H activation processes. The reaction of 1b with [Ir2Cl2(COE)4] (COE = cyclo-octene) affords the 18-electron iridium(III) dihydrido complex [IrH2Cl{κ3-C,P,P′-C(NCH2PCy2)2C10H6}], which forms [IrHCl2{κ3-C,P,P′-C(NCH2PCy2)2C10H6}] under acidic (HCl) conditions. In contrast, reaction...[Show more]
