2-(2′-Thienyl)pyridine (Hthpy) reacts with [Ir(CO)(MeCN)(PPh3)2]PF6(1) in dichloromethane at room temperature to give [Ir(CO)(Hthpy)(PPh3)2]PF6(2), which contains an N-bound Hthpy. Direct cyclometallation occurs when the chelating ligand reacts with 1 under reflux conditions in dichloromethane/2-methoxyethanol solution. The product [Ir(H)(thpy)(CO)(PPh3)2]PF6(3) can also be obtained through thermal rearrangement of 2. The structures of 2 and 3 have been determined by single crystal X-ray diffraction studies. © 1994.

Abstract
2-(2′-Thienyl)pyridine (Hthpy) reacts with [Ir(CO)(MeCN)(PPh3)2]PF6(1) in dichloromethane at room temperature to give [Ir(CO)(Hthpy)(PPh3)2]PF6(2), which contains an N-bound Hthpy. Direct cyclometallation occurs when the chelating ligand reacts with 1 under reflux conditions in dichloromethane/2-methoxyethanol solution. The product [Ir(H)(thpy)(CO)(PPh3)2]PF6(3) can also be obtained through thermal rearrangement of 2. The structures of 2 and 3 have been determined by single crystal X-ray diffraction studies. © 1994.File in questo prodotto:
