Protonation of cobalt, rhodium, and iridium hydrides with fluorocarbon acids. Synthesis, reactivity, and dynamic properties of (Ph3P)3Rh+ and its derivatives

Protonation of a variety of Co, Rh, and Ir hydrides with the fluorocarbon acids H2C(SO2CF3)2, PhCH(SO2CF3)2, HN(SO2CF3)2, H2C(SO2C8F17)2, and C8F17SO3H is reported. The Co and Ir hydrides form cationic dihydrides. Protonation of (Ph3P)4RhH affords [(Ph3P)3Rh][HC(SO2CF3)2]. The stereochemical nonrigidity of [(Ph3P)3Rh]+ in solution has been characterized by 31P DNMR. Reactions of this 14-electron Rh(I) compound are described, including the solid-state carbonylation to yield [(Ph3P)3Rh(CO)2] [HC(SO2CF3)2]. Carbon monoxide in the dicarbonyl salt is labile, and it dissociates in solution to give [(Ph3P)3Rh(CO)] [HC(SO2CF3)2]. Fluorocarbon acids having long-chain perfluoroalkyl groups are useful in synthesizing salts that have high solubility in aromatic hydrocarbons.
