Photochemical oxidative addition of B-H bonds at ruthenium and rhodium

摘要

Metal phosphine hydrides of type RuP_4H_2 and RhP_3H_3 react photochemically with HB(pin) (pin = pinacolate) to form metal boryl hydride complexes via 16-electron intermediates generated by H_2 loss; the second order rate constants for reaction of the intermediates with HB(pin) are even larger than those for reaction with Et_3SiH.
