Abstract

[Cp*RhCl2]2 is a very effective catalyst for C-C coupling of quinones with aryl and alkyl boronic acids under mild conditions. This reaction provides a practical, efficient method for the synthesis of aryl- and alkylquinones in good yields at room temperature and under base-free conditions.
