A new, convenient and efficient transition metal-free synthesis of S-alkyl dithiocarbamates through one-pot reaction of N-tosylhydrazones, carbon disulfide and amines is reported. Tosylhydrazones derived from various aromatic and aliphatic ketones or aldehydes were tested and gave dithiocarbamates in good to excellent yields. The tosylhydrazones can be generated in situ without isolation, which provides
据报道,通过N-甲苯磺酰基hydr,二硫化碳和胺的一锅反应,一种新的,方便且有效的无过渡金属的S-烷基二硫代氨基甲酸酯的合成方法。对衍生自各种芳族和脂族酮或醛的甲苯磺酰hydr进行了测试,并以良好或优异的收率得到了二硫代氨基甲酸酯。甲苯磺酰hydr可以原位生成而无需分离,这提供了一种更简单的一锅法,可在羰基化合物,二硫化碳和胺存在下,通过羰基化合物,二硫化碳和胺的反应来合成二硫代氨基甲酸酯。4-甲基苯磺酰肼。
