Abstract

Abstract Pyrolysis of octamethyl-1, 2-disilacyclobutane (I) has been shown to proceed by a unimolecular isomerisation involving a biradical which undergoes internal hydrogen- abstraction. Kinetic data were obtained for this pyrolysis and for that of the oxidation product of I, octamethyl-1, 3-disila-2-oxacyclopentane (II). A few additional experiments indicated that intermediates with π-bonds to silicon may be generated by photolysis of I. The ...
