Reaction of α-(1H-1,2,4-triazol-1-yl)acetophenone with phenyl isothiocyanate in the presence of a base and subse- quent alkylation leads to the ketene S,N-acetal(2),(4),(7), (8);thiazolidone(3),thiazolidine(5)and 1,3...Reaction of α-(1H-1,2,4-triazol-1-yl)acetophenone with phenyl isothiocyanate in the presence of a base and subse- quent alkylation leads to the ketene S,N-acetal(2),(4),(7), (8);thiazolidone(3),thiazolidine(5)and 1,3-thiazine(6),展开更多
The insertion reaction of phenyl isothiocyanate into the Ln S bond was studied. Phenyl isothiocyanate reacted with [(CH 3C 5H 4) 2Sm(SPh)(THF)] 2 to give the title complex, (CH 3C 5H 4) 2Sm[SC(SPh)NPh](THF),...The insertion reaction of phenyl isothiocyanate into the Ln S bond was studied. Phenyl isothiocyanate reacted with [(CH 3C 5H 4) 2Sm(SPh)(THF)] 2 to give the title complex, (CH 3C 5H 4) 2Sm[SC(SPh)NPh](THF), in good yield, which was characterized by elemental analyses, IR, 1H NMR and X ray structural determination. The crystal structure analysis of complex shows that samarium atom is coordinated by two CH 3C 5H 4 groups, one O atom of THF, and N and S atoms from the SC(SPh)NPh ligand to form a distorted trigonal bipyramidal geometry.展开更多
In ionic liquid [Bmim][BF4], a series of disubstituted and trisubstituted thiourea derivativeswere synthesized from phenyl and butyl isothiocyanate with a variety of amine in excellent yield.
