Palladium–phosphinous acid-catalyzed Sonogashira cross-coupling reactions in water

Palladium–phosphinous acid-catalyzed Sonogashira cross-coupling reactions in water A palladium–phosphinous acid-catalyzed Sonogashira cross-coupling reaction that proceeds in water under air atmosphere in the absence of organic co-solvents has been developed. Disubstituted alkynes have been prepared in up to 91% yield by POPd-catalyzed coupling of various aryl halides including chlorides in the presence of tetrabutylammonium bromide and pyrrolidine or NaOH. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Organic & Biomolecular Chemistry Royal Society of Chemistry

Abstract

A palladium–phosphinous acid-catalyzed Sonogashira cross-coupling reaction that proceeds in water under air atmosphere in the absence of organic co-solvents has been developed. Disubstituted alkynes have been prepared in up to 91% yield by POPd-catalyzed coupling of various aryl halides including chlorides in the presence of tetrabutylammonium bromide and pyrrolidine or NaOH.
