✦ Synopsis

Nickel-Catalyzed Regio-and Stereoselective Homo 1,4-Dialkenylation of Conjugated Dienes.

-An unusual regio-and stereoselective nickelcatalyzed reaction of conjugated dienes with iodoenones (II) is presented leading to homodialkenylation of the dienes. For butadiene (I) only 1,4-addition products with Z geometry are observed, while cyclic dienes (IV) give with ester (VI) 1,4-products as the major species. The effects of reaction conditions on the yield of product (IIIb) are studied in detail.
