摘要：

Metal phosphine hydrides of type RuP4H2 and RhP3H3 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 Et3SiH.
