铑配合物RhH（PPh3）（4）和Rh（acac）（CH2=CH2）（2）催化异腈与硫的硫化反应，高产率地得到异硫氰酸酯。金属催化的反应在丙酮中是快速的，并且在大多数情况下在3小时内完成。反应存在诱导期，在丙酮中预热硫1.5h后，诱导期消失.为了比较反应性，检查了在该转化中使用几种有机多硫化物。(C)2005爱思唯尔有限公司保留所有权利。
Rhodium complexes RhH(PPh3)(4) and Rh(acac)(CH2=CH2)(2) catalyze sulfuration of isonitrile with sulfur giving isothiocyanates in high yields. The metal-catalyzed reaction is rapid in refluxing acetone, and completes within 3 h in most cases. The reaction exhibits induction period, which disappeared by preheating sulfur in refluxing acetone for 1.5 h. Use of several organic polysulfides in this transformation was examined in order to compare the reactivity. (C) 2005 Elsevier Ltd. All rights reserved.
