The interaction of a large number cyanide compounds (nitriles, thiocyanates and N, N-disubstituted cyanamides) with 2,6-disubstituted 1,4,3,5-oxathiadiazin-4,4-dioxides. The general regularities of the border and the feasibility of this reaction. It depends on the electronic properties of the substituents in the dioxide and cyanide. Replacing imine fragment occurs dioxide with strongly acceptor groups R1 (CCl3, CBr3, C6F5) and with weak acceptor or donor groups R2 (4-NO2C6H4, 4-ClC6H4, CH3). The reaction takes place under the action of a nucleophilic reagent with cyanogroups one side (4-ClC6H4, C6H5, (CH3)2CHS, piperidino, diethylamino, morpholino) and with strong acceptor radicals (CCl3) on the other hand. Structure of the reaction products proved by spectroscopic and elemental analysis. Dioxides with two strong acceptor substituents react with a nucleophilic cyanogroups for entirely different mechanism. In this case, the imine moiety substitution occurs.
