摘要：
An efficient cobalt-catalyzed geometrical isomerization of1,3-dienes is described. In the combination of a CoCl2precatalyst with anamido-diphosphine-oxazoline ligand, the geometrical isomerization ofE/Zmixtures of 1,3-dienes proceed in a stereoconvergent manner, affording (E)isomers in high stereoselectivity. This facile transformation features a broadsubstrate scope with good functional group tolerance and could be scaled up to the gram scale smoothly with a catalyst loading of 1mol %.
