&ITmeso&IT-Tetraaryl(porphyrinato)cobalt(III)-catalyzed Oxygenation of Disilanes under Aerobic Conditions
Cobalt(III) porphyrin-catalyzed oxygenation of disilanes is investigated. Five- and six-membered cyclic disilanes are readily oxygenated, providing the corresponding cyclic disiloxanes in 75%-quant yield. We propose a reaction mechanism involving intermediates with a Co(III)-Si bond based on spectroscopic analysis of the reaction mixtures.
