Abstract

A well-characterised 14-electron rhodium phosphine complex, [Rh(P iPr3)3][BArF4], which contains a ß-CH agostic interaction, is observed to undergo spontaneous dehydrogenation to afford [Rh(PiPr3)2(P iPr2(C3H5))][BArF4]; calculations on a model system show that while C-H activation is equally accessible from the ß-CH agostic species or an alternative ?-CH agostic isomer, subsequent ß-H-transfer can only be achieved along pathways originating from the ß-CH agostic form. © The Royal Society of Chemistry.
