Yegorova T. 1-methyltetrazolo[5,1-a]isoindole in reactions with maleic imides and acid chlorides

The dissertation is devoted to 1-methyltetrazolo[5,1-a]isoindole in reactions with maleic imides and acid chlorides. Cycloaddition of 1-methyltetrazolo[5,1-a]isoindole and 1,2-dimethyl-1,2,4-triazolo[5,1-a]isoindole with maleic imides was studied. It was shown that product of such coupling resulted from three consecutive processes. It was shown that in conditions of acylation by acid chlorides two products were formed: acyl-derivatives and dyes, not reported before - monomethincyanines, substituted near central carbon atom. Features of the influence of initial reagents ratio and the nature of substituent R in acylating agent (R = Alk, Ar, Het) on reaction course were established. Complex formation of cyanine dyes of tetrazoloisoindole group with metals was studied on example of ferrum(III) and nickel(II).
