Homogeneous catalysis, initiation

The sonochemistry of solutes dissolved in organic Hquids also remains largely unexplored. The sonochemistry of metal carbonyl compounds is an exception (57). Detailed studies of these systems led to important mechanistic understandings of the nature of sonochemistry. A variety of unusual reactivity patterns have been observed during ultrasonic irradiation, including multiple ligand dissociation, novel metal cluster formation, and the initiation of homogeneous catalysis at low ambient temperature (57). 

Having demonstrated that ultrasound can induce ligand dissociation, the initiation of homogeneous catalysis by ultrasound becomes practical. The...

Although there are many known hydride complexes that are important in homogeneous catalysis, relatively few photochemical studies were conducted on these compounds before we began our investigations. Because transition metal hydride complexes are used in homogeneous catalysis and might be used in the photoassisted production of H2 from water, we initiated a study of their photochemical properties.
