Reactions of Carbonyl Diisocyanate with Amides and Acids

Carbonyl diisocyanate (1) reacts with primary amides to give 1-acylated isocyanuric acids (5, 6).With secondary amides, 1 affords the rather instable oxadiazinediones 4, which for certain substituents rearrange to give triazines (5, 10).With nucleophiles, compounds 4 give oligourets, e.g. with ureas pentaurets (11, 12) were obtained.Carbonyl diisocyanate reacts with hydrogen halides to afford the crystalline urea-1,3-dicarbonyl halides 13a-c.Diverse products (16, 17, 24, 26) were obtained with carboxylic acids.In most cases oxadiazinediones (26) were isolated, which can be transformed with nucleophiles into acyl ureas 30, 31, biurets 32, and triurets 33.Acetylation of 26 leads to the reactive heterocycles 34.
