Abstract

Laser flash photolysis of [Ru(PPh3)3(CO)(H)2] 1 in benzene solution yielded transient [Ru(PPh3)3(CO)] which was observed by both microsecond UV/VIS and IR spectroscopy [λmax = 380 nm, v(CO) = 1845 cm-1] and reacted with H2 to reform 1 [k2 = (8.4 ± 0.4) × 107 dm3 mol-1 s-1]; photolysis of 1 with an ultrafast laser equipped with IR detection demonstrates that reductive elimination of H2 and formation of [Ru(PPh3)3(CO)] is complete within 6 ps.
