A variety of 2-substituted thiophenes is readily obtained from 2-(2-thienyl)-4H-3,l-benzothiazin-4-one (2), which is formed when thiophene reacts with methyl2-isothiocyanatobenzoate (1) in the presence of anhydrous stannic chloride.
从2-(2-噻吩基)-4 H -3,1-苯并噻嗪-4-酮(2)可以很容易地获得各种2-取代的噻吩,当噻吩与2-异硫氰酸根合苯甲酸甲酯(1)反应时形成无水氯化锡的存在。
