of a series of four-coordinate complexes (CF3PCP)Ir(L) (L = CO, DBU, nbe, coe, MeP(C2F5)2 (dfmp)) and five-coordinate complexes (CF3PCP)Ir(L)(L′) (L = L′ = CO, dfmp, nbd, cod, (C2F5)2PCH2CH2P(C2F5)2 (dfepe); L = PhCN, L′ = C2H4) from dehydrohalogenation of (CF3PCP)Ir(C2H4)(H)Cl with Et3N in the presence of trapping ligands is reported. (CF3PCP)Ir(L) and (CF3PCP)Ir(L)2 for L = CO, dfmp have been structurally
