The synthesis of isothiocyanates (ITCs) by employing polymer-supported 1,4,2-oxathiazoles is described. The ITCs are obtained in moderate yields and high purity through a reagentless, thermal fragmentation of polymer-supported 1,4,2-oxathiazoles that are obtained by trapping nitrile oxides with polymer-supported thiocarbonates.
描述了使用聚合物负载的 1,4,2-恶噻唑合成异硫氰酸酯 (ITC)。通过聚合物负载的 1,4,2-恶噻唑的无试剂热裂解获得中等产率和高纯度的 ITC,聚合物负载的 1,4,2-恶噻唑是通过用聚合物负载的硫代碳酸盐捕获腈氧化物而获得的。
