Abstract
The reaction of diazomethane and O-acylisonitrosomalonates gave Δ2-1,2,3-triazoline-5,5-dicarboxylic acid esters, the rates of formation and thermal stabilities of which are determined by the character of ths substituent attached to the oxygen atom. Thermolysis of the triazolines leads to mixtures of 1-acyloxyaziridine-2,2-dicarboxylic acid esters and isomeric dialkyl O-acylisonitrososuccinates; acidolysis with BF3·Et2O makes it possible to obtain exclusively aziridines. The acidic decompositions of dimethyl 4-methyl-Δ2-1,2,3-triazoline-5,5-dicarboxylate, which was obtained from the reaction of diazoethane and dimethyl O-tosylisonitrosomalonate, leads to dimethyl α-tosyloxyamino-α-vinylmalonate. A dependence of the spin-spin coupling constants (SSCC) of the protons of the aziridine ring on the electronegativities of the substituents attached to the oxygen atom was observed.
