[Photochemistry of intermolecular C-H bond activation reactions]. Progress report, [September 15, 1994--March 15, 1995]
Since the last progress report (March 15, 1994), attention was paid to the solution photochemistry of (HBPz*{sub 3})Rh(CO){sub 2} (Pz* = 3,5-dimethylpyrazolyl) at different excitation wavelengths and in various hydrocarbon solvents (n-pentane). Absolute quantum efficiencies were obtained for the intermolecular C-H bond activation at different wavelengths and temperatures. Results indicate that there are two excited states with different reactivities and two reaction channels. The intermediate that is highly reactive toward hydrocarbon C-H bonds is probably the monocarbonyl (HBPz*{sub 3})Rh(CO) species. Related studies are being carried out on tungsten(IV) eight-coordinate-chelate complexes.
