An efficient and convenient palladium-catalyzed C–H bond oxidative sulfenylation of indoles and related electron-rich heteroarenes with arylboronicacids and elementalsulfur has been described. This procedure provides a useful and direct approach for the assembly of a wide range of structurally diverse 3-sulfenylheteroarenes with moderate to excellent yields from simple and readily available starting
Redox Isomerization via Azomethine Ylide Intermediates: <i>N</i>-Alkyl Indoles from Indolines and Aldehydes

Indolines react with aromatic and heteroaromatic aldehydes to yield N-alkyl indoles in a benzoic acid catalyzed redox isomerization reaction. Azomethine ylides are intermediates in this process which was established by intramolecular [3 + 2] trapping experiments.

Herein we report a microwave assisted Ru(III)/TBHP-mediated reaction of indoles with tetramethylurea (TMU) synthesizing symmetrical as well as unsymmetrical bis(indolyl)methanes, where TMU acts as a methylenating agent. This is the first report where TMU is used as a methylene source. Moreover, the synthesis of unsymmetrical bis(indolyl)methanes by using a carbon precursor is also reported herein for
