Abstract
PURPOSE:To remarkably stabilize the titled precursor at the time of storing it, and to release rapidly a base by heating it by composing the org. base of a compd. having 2-4 partial structures derivated from a specified guanidine. CONSTITUTION:The org. base contains 2-4 the partial structures corresponding to an atomic group (a residual group) except 1 or 2 hydrogen atoms from the guanidine shown by the formula, and is composed of a di or a tetra acidic base having one or more hydrocarbon or heterocyclic residual groups as the coupling group of said partial structure. In the formula, R<1>-R<5> are each hydrogen atom or alkyl group, etc., and the optional two groups selected from the groups R<1>-R<5>, together with each other may form a 5 or 6 membered nitrogen contg. heterocyclic ring. Thus, the titled precursor maintains its crystal structure until the temp. raises to a prescribed temp., and when the crystal structure is collapsed by melting or dissolving, the decarboxylation reaction of a carboxylic acid occurs suddenly resulted in releasing the base.
