3-triazoles and amines is reported. This transformation undergoes silver-catalyzed or metal-free thermally promoted denitrogenation of N-sulfonyl-1,2,3-triazoles to afford N-sulfonylketenimine intermediates and subsequent nucleophilic addition with amines. The amine plays dual roles as base and nucleophile. A highly efficient synthesis of N-sulfonylamidines from N-sulfonyl-1,2,3-triazoles and amines is reported
摘要 据报道,由N-磺酰基-1,2,3-三唑和胺可高效合成N-磺酰胺基。该转变经历N-磺酰基-1,2,3-三唑的银催化的或无金属的热促进的脱氮作用,以提供N-磺酰基酮亚胺中间体,并随后与胺进行亲核加成。胺起碱和亲核试剂的双重作用。 据报道,由N-磺酰基-1,2,3-三唑和胺可高效合成N-磺酰胺基。该转变经历N-磺酰基-1,2,3-三唑的银催化的或无金属的热促进的脱氮作用,以提供N-磺酰基酮亚胺中间体,并随后与胺进行亲核加成。胺起碱和亲核试剂的双重作用。
