A new practical procedure of imination for sulfide has been developed. The treatment of (N-tosylimino)-phenyl-λ3-iodane, PhINTs, with various sulfides in the presence of a catalytic amount of I2 under metal-free conditions affords the corresponding N-tosylsulfilimine compounds with moderate to good yields. This facile transfer procedure of the sulfonylimino group can also be applied to triphenylphosphine
已开发出一种新的硫化物亚胺化实用程序。在无金属条件下,在催化量的 I2 存在下,用各种硫化物处理(N-甲苯磺酰基亚胺基)-苯基-λ3-碘烷 PhINTs,得到相应的 N-甲苯磺酰基磺胺化合物,产率中等至良好。磺酰基亚氨基的这种简便转移程序也可应用于三苯基膦,以高产率生产相应的亚氨基三苯基膦。根据反应机理研究,(N-tosylimino)-苯基-λ3-碘在该条件下亚胺化为硫化物的过程可能涉及反应机理中的自由基步骤。
