The decomposition of a series of benzylidene, methylidene, and 3-phenylindenylidene complexes has been probed in alcohol solution in the presence of base. Tricyclohexylphosphane- containing precatalysts are shown to yield [RuCl(H)(H-2)(PCy3)(2)] in isopropyl alcohol solutions, while 3-phenylindenylidene complexes lead to eta(5)-(3-phenyl)indenyl products. The potential-energy surfaces for the formation of the latter species have been probed using density functional theory studies.

Abstract
The decomposition of a series of benzylidene, methylidene, and 3-phenylindenylidene complexes has been probed in alcohol solution in the presence of base. Tricyclohexylphosphane- containing precatalysts are shown to yield [RuCl(H)(H-2)(PCy3)(2)] in isopropyl alcohol solutions, while 3-phenylindenylidene complexes lead to eta(5)-(3-phenyl)indenyl products. The potential-energy surfaces for the formation of the latter species have been probed using density functional theory studies.File in questo prodotto:
