Abstract
A well-characterised 14-electron rhodium phosphine complex, [Rh(P(i)Pr(3))(3)][BAr(4)(F)], which contains a beta-CH agostic interaction, is observed to undergo spontaneous dehydrogenation to afford [Rh(P(i)Pr(3))(2)(P(i)Pr(2)(C(3)H(5)))][BAr(4)(F)]; calculations on a model system show that while C-H activation is equally accessible from the beta-CH agostic species or an alternative gamma-CH agostic isomer, subsequent beta-H-transfer can only be achieved along pathways originating from the beta-CH agostic form.
