Abstract

Activated and deactivated aryl and heteroaryl chlorides are efficiently cross-coupled with potassium alkenyltrifluoroborates using 4-hydroxyacetophenone oxime derived palladacycle as precatalyst, Binap as ligand, and Cs2CO3 as base in DMF at 120 °C. The corresponding cross-coupled compounds are obtained in good yields and with high regio- and diastereoselectivity.
