The aminolysis process of sulfinamoyl derivatives was investigated with sulfinamoyl esters. An intermediate sulfine was unambiguously evidenced by formation of a Diels-Alder type adduct. The aminolysis leads to final thiooxamate products. A carbophilic addition was suggested for the reaction with secondary amines. With sulfinamoyl, -sulfones and -sulfonamides, a thiourea is formed resulting from a
