SULFOALKYLATION OF 1,2-DIHYDRO-3,6-PYRIDAZINE- AND 2,3-DIHYDRO-1,4-PHTHALAZINEDIONES AND THEIR N-PHENYL DERIVATIVES BY 1,3-PROPANESULTONE AND BROMOALKANESULFONATES

Abstract

When 1,2-dihydropyridazine-3,6-, 2,3-dihydrophthalazine-1,4-, 1-phenyl-1,2-dihydropyridazine-3,6-, and 2-phenyl-2,3-dihydrophthalazine-1,4-diones react with 1,3-propanesultone and bromoalkane-sulfonates, depending on the nature of the sulfoalkylating agent in the case of 1,2-dihydropyridazine-3,6- and 2,3-dihydrophthalazine-1,4-diones, either N,O- or O,O¹-disulfoalkylated compounds may be formed, while O-monosulfoalkylated reaction products may be formed in the case of the N-phenyl-substituted derivatives of the above-indicated azinediones.
