Carbanions containing leaving groups at the carbanion centers react with 1.2.4-triazine and its derivatives according to the vicarious nucleophilic substitution scheme replacing hydrogen atoms in 5-, 3-. or &positions with the carbanion moiety. It is denionstrated that thc activity of various positi
