N-Alkylation of tosylhydrazones via a metal-free reductive coupling procedure
摘要:
A simple metal-free route for the N-alkylation of tosylhydrazones is described via the NaOMe-promoted reductive coupling of tosylhydrazones under mild conditions. A wide variety of N-alkylated tosylhydrazones were obtained in moderate to good yields. (C) 2012 Elsevier Ltd. All rights reserved.
