Cationic iridium phosphines partnered with [closo-CB11H6Br6](_): (PPh3)(2)Ir(H)(2)(closo-CB11H6Br6) and [(PPh3)(2)Ir(eta(2)-C2H4)(3)][closo-CB11H6Br6]. Relevance to counterion effects in olefin hydrogenation
Treatment of [(PPh3)2Ir(COD)][closo-CB11H6 Br6] with H2 in CH2Cl2 solution affords crystallographically characterized (PPh3)2Ir(H)2(closo-CB11 H6Br6), in which the weakly coordinating carborane anion is bound to the metal center. In solution the anion rapidly dissociates/recombines with the metal ce...
