Facile Access of Olefins from Ketones and Arylboroxines Enabled by Rhodium Catalysis.

Olefination of carbonyl compounds is a typical strategy for the synthesis of olefins. Herein, we reported a rhodium‐catalyzed cross‐coupling reaction of ketones with arylboroxines for straightforward access of olefins. The reaction displays a good functional group tolerance and affords the corresponding products in good to excellent yields. Addition and elimination are suggested as the indispensable steps in catalytic cycle by preliminary mechanistic experiments. This reaction provided a complementary method in catalytic construction of olefins from ketones and organoboron compounds. [ABSTRACT FROM AUTHOR]
