Abstract. The arylcyanate benzoxazoline-2-thione (1) reaction in the presence and absence of the tertiary amines yields 1-aryloxyimjnocarbonylbenzoxazoline-2-thione(2) and 2- thiocyanatobenzoxazole (4). A mechanism is proposed based on the influences of the reactants concentration, the concentration and basicity of tertiary amines, the solvent-water concentration, the arylcyanate substituents electronic effects on the reaction rate and the ...
