In the first application of ultrafast TRIE spectroscopy (that is, with time-scales of 10 to 10 s), reductive elimination and oxidative addition of H2 have been traced following flash photolysis of the related ruthenium carbonyl dihydride complex Ru(PPh3)3(CO)H2 in benzene solution (90). This precursor is of particular note because it is known to catalyze insertion of alkenes into C-H bonds at the unsaturated carbon center of alkenes or arenes in a position /3 to a carbonyl group. The course of events has been monitored from excitation with an ultrafast UV laser (giving pulses at A = 304 nm with an energy of...
