✦ Synopsis

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 positions of the triazine ring toward nucleophilic substitution of hydrogen dccreases in this order. The reaction provides an elficient way of introduction of functionalized alkyl substituents into the triazine ring.
