An object of the present invention is to provide a compound which is capable of attaining a composition having high storage stability without reacting with a base-reactive compound, even in the case of storage for a long period of time in a mixed state with the base-reactive compound, such as an epoxy-based compound, as well as capable of generating a strong base (guanidines, biguanides, phosphazenes or phosphoniums) by irradiation of light (active energy rays) or heating; a base generator comprising the compound; and a base-reactive composition comprising the base generator and the base-reactive compound.
The present invention relates to the compound represented by the general formula (A); the base generator comprising the compound; and the base-reactive composition comprising the base generator and the base-reactive compound.

Chiralbisphosphazides complexed with lithium salts efficiently catalyze the direct enantioselective 1,4-addition of dialkyl malonates to acyclic enones. Spectroscopic studies on the stoichiometry of the bisphosphazide and lithium salt have indicated the formation of a 1:1 species as the active enantioselectivecatalyst. It is suggested that the catalyst generates a complex of the protonated phosphazide

Phosphorylation of naphthodiols with hexaisopropyl- and hexabutyltriamides of phosphorous acid was studied for the first time. The features of these reactions were considered. A comparative analysis of the properties of the synthesized naphthophosphacyclophanes and dismutation of bisamidophosphites was performed.

This invention relates to a process of catalytically converting nitrobenzene to 2-amino-3H-azepines by the reaction of the nitrobenzene with trisaminophosphine and an amine of the formula HNR'.sub.2, where R' is lower alkyl containing 1 to 6 carbon atoms. In addition, this invention concerns the catalytic hydrogenation of 2-amino-3H-azepine to epsilon caprolactam.
