2-chloro-3-isothiocyanato-prop-1-ene Usage And Synthesis

Chemical Properties

colorless liquid, bp73～76℃/2.4kpa, insoluble in water, soluble in organic solvent.

Uses

2-chloro-3-isothiocyanato-prop-1-ene is an intermediate of insecticides thiamethoxam and clothianidin.

Synthesis

2-chloro-3-isothiocyanato-prop-1-ene was prepared by reacting 2,3-dichloropropene and sodium thiocyanate in acetonitrile, heating and refluxing for 3.5h in the presence of a catalyst. Reaction equation:
CH₂=CHClCH₂Cl+NaSCN→CH₂=CHClCH₂NCS
