Abstract

The preparation of a library of bis-imidazolium salts and corresponding palladium complexes is reported. These complexes are screened as catalysts in the Suzuki reaction between 4-bromoanisole and phenylboronic acid. Each step is performed in parallel using a 24-position silicon carbide plate and microwave heating. The plate allows for use of standard glass vials as reaction vessels. The ease and speed of operation show the potential for microwave heating in conjunction with the silicon carbide plate as a tool for catalyst screening. (C) 2009 Elsevier Ltd. All rights reserved.
