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.

A variety of R3PI4 compounds have been synthesized and characterised by elemental analysis, NMR and visible spectroscopy. Apart from Ph3PI4, all are reported for the first time. X-Ray crystallographic studies on two of these materials, Pri3PI4 and (Prn2N)3PI4, revealed different solid-state structures which are, in turn, different to both the two polymorphs of Ph3PI4 and Fc3PI4 (Fc = ferrocenyl) the crystal structures of which have been previously reported. The compound Pri3PI4 exists as [(IPPri3)2I3]I3, which contains two [IPPri3]+ cations independently weakly linked to one of the two terminal iodine atoms of the same triiodide anion. The structure also contains a discrete triiodide anion. The compound (Prn2N)3PI4 exhibits very little anion–cation interaction. Of the two molecules present in the asymmetric unit, one exhibits no anion–cation interaction, while the other shows only a very weak contact [d(I–I)] (cation–anion) = 3.944(2) Å.

The first tricyclie fused triazaphosphole derivatives, namely, 2,3-disubstituted 2,3-dihydro[1,3]benzothiazolo[3,2-d][1,2,4,3]triazaphospholes, were obtained by cyclocondensation of 2-phenylhydryzono- or 2-hydrazono-2,3-dihydro-1,3-benzothiazoles with tris[dialkylamino]-phosphines.

The reactions of the tris-dialkylamino phosphines (Et2N)3P and (nPr2N)3P, and the pyrrolidinyl substituted phosphines (C4H8N)3P and tBuP(NC4H8)2, with I2 and (Ph2Se2I2)2, have been reported. The reactions with diiodine lead to the formation of [R3PI]I adducts, which are essentially ionic, but show a tendency to display long, soft–soft, I⋯I interactions in the solid state.
