Functionalized arylcopper reagents react readily with alkenyl sulfonates in the presence of catalytic amounts of Fe(acac) 3 (10 mol%) providing the expected cross-coupling products in good yields. Ester or cyano group are tolerated. This cross-coupling can be performed with dienyl sulfonates leading to the corresponding substituted dienes.
The Ni(0)-catalyzed cross-coupling of alkenyl methylethers with boronicesters is described. Several types of alkenyl methylethers can be coupled with a wide range of boronicesters to give the stilbene derivatives.
