The pyrolysis of a series of cholesteryl xanthates has been studied. For the series, the first order rate constants have been determined, and from them, the Hammett parameter, p. In addition the pyrolyses of several closely related compounds, cholesteryl acetate, methyl trithiocarbonate, ethyl carbonate, phenyl carbamate and benzoate, have been studied. All showed first order rate constants, and the acetate and carbonate pyrolyses had negative ...
