Derivatives of the triaminoguanidinium ion, 4. O-Sulfonylation of N,N′,N″-tris(hydroxybenzylidenamino)guanidinium ions

Abstract

Abstract All hydroxy groups of the N,N′,N″-tris(4-hydroxybenzylidenamino)guanidinium and N,N′,N″-tris(2,4-dihydroxybenzylidenamino)guanidinium ions could be sulfonylated in good yields to obtain three-fold or six-fold substituted and functionalized derivatives. The 2,4-dihydroxyphenyl containing precursors have been used to construct branched three-armed guanidinium derivatives bearing six dansyl or anthraquinone moieties.
