Versuchsvorschrift

Styrene in an amount of 2.1 grams and 11.65 grams of manganic acetate, Mn(C2H3O2)3.2H2O, comprising two equivalents of Mn+3 based on titration value, were refluxed under nitrogen in 200 milliliters of propionic acid containing 20 grams of potassium propionate. In less than an hour, a 50% yield of alpha-methyl-gamma-phenyl butyrolactone was obtained.
