Abstract

Irradiation of Rufdmpe^H: (dmpe = (CHa^PCHaCHaPÍCHa^) in cyclohexane solution with a picosecond pulsed laser at 300 nm leads to immediate formation of Ru(dmpe)2 and H2. The experiments show that metal-hydrogen bond cleavage, H-H bond formation, and rearrangement of the metal-phosphine skeleton occur within the instrument rise time of ca. 16 ps. A partial decay of the transient with a rate constant of 2.5 X 109 s-1 is also observed. The transient spectral data obtained for the short- and long-lived transients are similar.
