Redistribution Reactions of Methylsiloxanes Catalyzed by Transition Metal Complexes.
Abstract
Redistribution reactions of a variety of hydrogen-substituted siloxanes are catalyzed by various transition metal complexes of iridium and rhodium. The products arise from breaking and remaking of Si-C, Si-H, and Si-O bonds. Siloxanes not possessing a Si-H bond are inert under the conditions studied. The most favored reaction pathway appears to preferentially scramble the groups directly attached to the silicon bearing the hydrogen atom. A new cyclo-iridiadisiloxane, L2(CO)(H)-Ir(SiMeROSiMeR) (L = Ph3P, R = Me3SiO) is reported. This compound exists in three isomeric forms as a consequence of the spatial arrangements of the R and Me groups on the ring. (Author)
