PHOTOLYSIS OF AN ARYLALKYL-TRIAZENIDO-PLATINUM-Ⅳ COMPLEX

摘要

The photolytic decomposition of tetrakis(1-phenyl-3-hexyl-triazenido)-platinum(Ⅳ) is studied in a variety of media, and found to proceed according to simple first order kinetics. Two excimer laser wavelengths, an excimer-laser pumped dye laser, and a broadband mercury lamp are used for excitation. As referred to the incident power, selective irradiation near the complex-specific absorption maximum is found to be most efficient for inducing the photolytic decomposition. A different influence of degassing and oxygen saturation is observed for tetrahydrofurane and for technical siloxane solvents. To elucidate the origins of the observed behaviour, decomposition products of the complex, and products of hydrosilylation reactions catalyzed by this compound, are identified by GC/MS analysis.
