Abstract

The charges on the reaction centers in 2-amino-4-methylthiazole and 5-aminotetrazole, which predetermine the pathway of their charge-controlled reaction with tropylium tetrafluoroborate, were determined by AM1 quantum-chemical calculations. Previously unknown 4-methyl-5-(cyclohepta-11,31,51-trienyl)-2-aminothiazole and 5-(N,N-dicyclohepta-11,31,51-trienyl)aminotetrazole were synthesized.
