abstract |
The triphenylsiloxy complex MoO2(OSiPh3)(2) and a related polyhedral metallasiloxane formulated as [MoO2(O2SiPh2)](n) have been tested as catalysts for the liquid phase epoxidation of cyclic olefins by tert-butylhydroperoxide at 55 degreesC. The initial activities increased in the order 1-octene < trans-2-octene < cyclododecene < cyclooctene and the corresponding epoxides were the only observed products. The best results were obtained without the addition of any co-solvents (other than decane), forming solid-liquid systems. Cyclooctene oxide was obtained in quantitative yield within 7.5 h of reaction, and the solid catalysts could be recycled without measurable loss of activity. (C) 2002 Elsevier Science B.V.
