The method for synthesis of 3,4,4-trichlorobut-3-ennitrile has been improved. The substitution products of internal chlorine atom by azido group, monoethanolamine fragment and also its esters with 5-( p-tolyl)isoxazole- and 4,5-dichloroisothiazole-3-carboxylic acids have been prepared. It has been found that HCl cleaves C-N bond in esters producing hydrochlorides of isothiazole-3- and isoxazole-3-carboxylic acid aminoesters, which. Under acylation by isoxazolyl- and isothiazolyl carbonyl chlorides formed mixed amido esters with different azole moieties.Усовершенствован способ синтеза 3,4,4-трихлорбут-3-еннитрила на основе доступной 3,4,4-трихлорбут-3-еновой кислоты - продукта превращений трихлорэтилена.
