Abstract An effective method is proposed for the production of the N,S-acetals of diacylketenes and acyl(alkoxycarbonyl)ketenes, based on the addition of methylene-activeβ-diketones andβ-ketoesters to alkyl and aryl thiocyanates catalyzed by Ni(2+) acetylacetonate. Methods are indicated for the synthetic utilization of diacetylketene N,S-acetals and include their conversion to ketene aminals, chelation with boron compounds, and deacylation of derivatives of monoacetylketene with methanol in the presence of Co(2+) acetate.
