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 [λ_max = 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.
