Mechanism of acid-catalysed alcoholysis of epoxides. Part II. Methanolysis of 1,1-diphenylethylene oxide
Abstract
Rate coefficients have been determined for the acid-catalysed methanolysis of 1,1-diphenylethylene oxide at –64, –54, and –44°, and the value of the entropy of activation (ΔS‡), –0·6 cal mol–1 K–1, is interpreted as indicating the occurrence of an A1 mechanism or a borderline A1 mechanism. The reaction was followed by g.l.c.
