✦ Synopsis
Title compounds give a-unsaturated carbonyl compounds by treatment with basic alumina in dichloromethane or diethylether. Ck'-Enones are thus obtained in high yield at room temperature.

Treatment of fl, fl -disubstituted enamines with potassium permanganste suppocted on neutral alumina leads to a mild and selective oxidative cleavage reaction which produces ketones and formamides. The ketones can be isolated in high yield and purity by a simple workup procedure. The oxidizing agent
