The syntheses of Ir(i) and Ir(iii) complexes incorporating the electron-withdrawing pincer ligand (1,3-C6H4(CH 2P(CF3)2)2) (CF3PCPH) with (PPh3)3Ir(CO)H and subsequent chemistry are reported. Under ambient conditions, reaction of 1 equiv. CF3PCPH with (PPh3)3Ir(CO)H gave the mono-bridged complex [Ir(CO)(PPh3)2(H)]2(μ-CF3PCPH) (1). Reaction of (PPh3)3Ir(CO)H with excess CF 3PCPH and MeI gave the doubly-bridged complex [Ir(CO)(PPh 3)(H)]2(μ-CF3PCPH)2 (2), whereas the tetrameric oligomer [Ir(CO)(PPh3)(H)]4(μ-CF 3PCPH)4 (2-sq) was obtained from a 1:1 ligand:metal mixture in benzene in the presence of excess MeI. At higher temperatures (165 °C) the reaction of CF3PCPH with (PPh3) 3Ir(CO)H afforded the 5-coordinate Ir(i) complex (CF 3PCP)Ir(CO)(PPh3) (3). Complex 3 shows mild catalytic activity for the decarbonylation of 2-naphthaldehyde in refluxing diglyme (162 °C). The Royal Society of Chemistry 2011.
