Abstract
Dibromocyclopropanes, prepared by addition of dibromocarbene to cyclic olefins, give unsaturated ketones, with ring expansion, when treated with silver sulphate in concentrated sulphuric acid at room temperature. Mild hydrogenation of a dibromocyclopropane gave equivalent amounts of the monobromocyclopropane and of a ring-opened bromine-free compound.Keywords
