The formate ester of benzoin (1) and the methyl ethers of benzoin and aniso
in (2, 3) have been converted separately under thermal gas-phase conditions
cleanly into 1,2-diarylethanone and have given, respectively, the followin
g Arrhenius log A (s(-1)) and E-a (kJ mol(-1)): 10.11 and 132.0, 11.29 and
173.0, and 11.85 and 151.1. A plausible mechanism is suggested to account f
or these transformations based on the kinetics and products of reaction.
