Metal free sulfenylation of active methylene compounds and indole: TBATB mediated synthesis
摘要:
The present work addresses a development of metal free one pot direct method for sulfenylation of active methylene compounds and indole. The reaction might proceed through sulfenyl bromide as an intermediate, which initiates the C-S bond formation. The reaction was performed using tetrabutylammonium tribromide (TBATB) as a brominating agent, CH2Cl2 as a solvent at room temperature. (C) 2015 Elsevier Ltd. All rights reserved.
