Kinetics of the pyrolsis of 1- methyl-1-vinyl-1 silacyclobutane; some observations on the stability of vinyl silyl radicals and silabutadienes
Abstract
Pyrolysis of the title compound to give ethene and a silabutadiene has the same Arrhenius parameters as pyrolysis of 1,1-dimethyl-1 silacycologutane whence the allylic stabillisation in a vinyl silyl radical is estimated to be ⩽29 kJ mol–1 some comments are also made on the stability of silabutadienses.
