The effect of pyrolysis of the acyl group substituted on α-position carbon in S-ethyl group of ethyl phenyl sulfoxide was investigated by using two kinds of substrates, 1-ethoxycarbonylethyl phenyl sulfoxide (1) and 1-ethoxycarbonyl-1-methylethyl phenyl sulfoxide (2) together with 2-methoxycarbonylethyl phenyl sulfoxide (4).The rate of pyrolysis of (1) was found to be about 740 ca. 890 times faster than that of ethyl phenyl sulfoxide (5), while (2) was 5700 times faster.The rate enhancement effect on α-ethoxycarbonyl group was larger than that on β-methoxycarbonyl group.Large deuterium kinetic isotope effect (kH/kD=5.5 for PhS(O)C(CD3)2CO2Et (3)) was observed.Activation energy for (2) is about 110 kJ/mol, which is just about the same as that of (5) (108 kJ/mol), while activation entropy lies in ca. 1 Jdeg-1 mol-1.Hammett plot for substituted (2) gave ?=0.69.These kinetic results reveal that the pyrolysis of the sulfoxides proceeds via a loose transition state involving advanced C-S bond cleavage.The remarkably large rate enhancement by α-carbonyl group might be due mainly to the conjugation of that group and developing double bond acidifying the β-proton in the transition state.Key words: Pyrolysis; elimination; mechanism; isotope effect; kinetics; sulfoxide,
