New mechanistic insights regarding Pd/Cu catalysts for the Sonogashira reaction: HRMAS NMR studies of silica-immobilized systems.

J Am Chem Soc

Organic Chemistry Department, University of Heidelberg, Im Neuenheimer Feld 270, 69120 Heidelberg, Germany.

Published: July 2006

The title technique, high-resolution magic angle spinning NMR of suspensions, constitutes a powerful new tool for investigating the structures and mobilities of immobilized species and, thus, for optimizing heterobimetallic catalyst systems, such as the Sonogashira coupling of terminal alkynes and aryl halides.
