Abstract

A variety of transformations involving C-C bond cleavage in iridium complexes is described. 1,1-Dimethylcyclopentane reacts with [IrH2(Me2CO)2L2]SbF6 (L = (p-FC6H4)3P, 1) to give first [(5,5-C5H4Me2)IrL2]SbF6(2) and then [(MeC5H4)lrMeL2]SbF6 (3). The corresponding 5,5-dimethylcyclopentadiene gives 1,2- and 1,3-diethylcvclopentadienyl complexes by a route that involves alkyl migration from ring to metal and back. 4,4-Dimethylcyclopentene also reacts to give 3 but the 3,3-isomer follows a different path to give [(MeC5H4)IrHL2]SbF6. Crystal structures of two diene complexes of type 2 are reported and mechanisms for the reactions observed are proposed.
