Abstract

Abstract Intermolecular couplings between arylboronic acids and activated alkenes catalyzed by a water-soluble tert-butyl amphos-rhodium complex were found to progress at room temperature and generated Heck-type products with high yields and excellent selectivity. Substitution on the alkene component encouraged the formation of products arising from a conjugate addition-protonation process. In the case of Heck product ...
