  摘要：

  Beta-halogeno-alpha,beta-unsaturated carbonyl derivatives were converted to the corresponding zinc organometallics 2a under mild conditions in THF (Zn dust, 25-45-degrees-C, 1-4h). These functionalized alkenylzinc iodides react with a variety of alkenyl and aromatic iodides affording the desired coupling products in 40-97% yield. The addition of a THF solution of CuCN.2LiCl to 2a affords the corresponding organocopper derivatives 2b which react with electrophiles, such as alkynyl and allylic halides, nitro olefins, enones, and chlorotrimethylstannane providing polyfunctional unsaturated carbonyl compounds in 71-95% yield. The insertion of chromium (II) chloride to beta-iodo and to some beta-(p-tosyl)enones in DMF furnishes new functionalized chromium (III) organometallics 2c which react with aldehydes providing gamma-hydroxy unsaturated carbonyl derivatives in 40-91% yield. The synthetic scope and the limitations of this methodology are discussed.

  Unmasked vinylogous acyl anion equivalents 2 were prepared by the insertion of zinc to various beta-halo, alpha,beta-unsaturated ketones and esters 1. The new reagents 2 react with various electrophiles in the presence of CuCN.2LiCl or catalytic amounts of Pd(0) complexes in excellent yields.
