An efficient and practical thiocarbonyl surrogate via combination of sulfur and chloroform has been developed. A variety of thiocarbamides and oxazolidinethiones have been established, including chiral thiourea catalysts and chiral oxazolidinethione auxiliaries with high selectivity. Meanwhile, pesticides Diafenthiuron (an acaricide), ANTU (a rodenticide), and Chloromethiuron (an insecticide) were practically synthesized through this method in gram scale. Dicholorocarbene, as the key intermediate, was further confirmed via a carbene-trapping control experiment.

The tri- and tetrasubstituted olefines 1, 2, 4, 7 - 15, and 19 react with CCl2 to give the dichlorocyclopropanes 22, 23, 25, 26a - 30a, and 33a - 37a in high yield, while the highly sterically hindered olefins 5, 6, and 21 show no reaction.In a few border
