実験手順

Octene-1 in an amount of 2.24 g. and 11.65 g. of manganic acetate, Mn(C2H3O2)3. 2H2O, (comprising two equivalents of Mn+3 based on titration value), were refluxed under nitrogen in 200 ml. propionic acid containing 20 g. potassium propionate. In less than an hour a good yield of alphamethyl-gamma-n-hexyl-butyrolactone was obtained.
