The reaction of ketene acetals (Ia-e) with ketene Was studied. Ketene diethylacetal (Ia) reacted with ketene to give 2,2-diethoxy-4-methyleneoxetane (IIa). Heating of IIa gave acetylketene diethylacetal (Va). Reaction of methylketene diethyladetal (Ib) with ketene afforded 3,3-diethoxy-2-methylcyclobutan-1-one (IIIb), besides acetylmethylketene diethylacetal (Vb). Phenylketene diethylacetal (Ic) was converted to acetylphenylketene diethylacetal (Vc) by reaction with ketene. Chloroketene diethylacetal (Id) afforded acetylchloroketene diethylacetal (Vd) and chloroacetylketene diethylacetal (VId). On treatment with diluted acid, Va-d and VId were hydrolyzed to give acetoacetate derivatives (VIIa-d, VIIId). VIIa-d reacted with aniline to give imino ether derivatives (IXa-d) in a good yield.
