Abstract

The enol of acetone, formed by disproportionation reactions of 1‐hydroxy‐1‐methylethyl radicals, is detected by NMR, spectroscopy during photoreactions of 3‐hydroxy‐3‐methyl‐2‐butanone in acetonitrile and of acetone in 2‐propanol and slowly tautomerizes to acetone. The photolysis of 3‐hydroxy‐3‐methyl‐2‐butanone is shown to proceed via Type I cleavage, predominantly from an excited triplet state.

The rates of gas-phase elimination reactions of methyl benzoylformate (1) and 3hydroxy-3-methyl-2-butanone (2) were obtained at T ϭ 600 K. The two substrates undergo unimolecular first-order elimination for which the Arrhenius equations are, respectively, log k ϭ 13.2 Ϫ 53270/(4.574 ϫ 600) for (1) a
