PREPARATION OF VINYL ISOTHIOCYANATES |
摘要 |
A process for preparing a vinyl isothiocyanate comprises contacting a halogen-substituted allyl thiocyanate, in solution and at an elevated temperature, with an acidic material which is either an acid or a halide or oxyhalide of an inorganic acid. The halogen-substituted allyl thiocyanate may be prepared from a dihalogenated alkene. The vinyl isothiocyanate may subsequently be converted to a thiazole.
