Title:
METHOD FOR PRODUCING ARYL COMPOUNDS
Document Type and Number:
WIPO Patent Application WO2002026665
Kind Code:
A3
Abstract:
Aryl compositions are advantageously produced by carrying out a cross-coupling reaction of a substituted aryl compound with a Grignard reagent and concurrent nickel catalysis. The inventive method is further characterized by using substituted aryl compounds and a novel nickel catalyst and slowly adding the Grignard reagent when the reaction temperature is reached.
