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...
N,N -bis(carboxymethyl) macrocyclic dilactams were synthesized in good to high yields from diamines and dianhydrides. Their ligand protonation and lanthanide complex stability constants were measured by a potentiometric method in aqueous solution. The lanthanide discriminating power of 12- and 18-membered macrocyclic dilactams derived from EDTA and EGTA measured by their stability constants were...
