efficient (one-step) oxidation is reported of commercially available tosylmethylisocyanide (TOSMIC) to form tosylmethylisocyanate, making this highly reactive bifunctional molecule a readily available synthetic reagent. Besides engaging in nucleophilic addition reactions with alcohols, amines, and thiols, tosylmethylisocyanate also reacts with carboxylic acids to form tosylmethylamides, which undergo substitution
据报道,市售的甲苯磺酰甲基异氰化物 (TOSMIC) 可以方便有效地(一步)氧化形成甲苯磺酰甲基异氰酸酯,使这种高反应性的双功能分子成为一种容易获得的合成试剂。除了与醇、胺和硫醇进行亲核加成反应外,甲苯磺酰基甲基异氰酸酯还与羧酸反应形成甲苯磺酰基甲基酰胺,后者在有机铜和有机镁试剂存在下发生取代反应。
