the first Grignard-type nucleophilic addition using olefinicalcohols as latent carbonyl groups, providing a higher yield of the corresponding secondary alcohol than the classical hydrazone addition to aldehydes does. A broad scope of unsaturated alcohols and hydrazones, including some complex structures, can be successfully employed in this reaction, which shows the versatility of this approach and

Various homoallylic alcohols and homobenzylic alcohols were prepared by the reaction between aldehydes and allylic or benzylic halides in the presence of samariumdiiodide. This iodide is also a very good reagent for formation of pinacols from aldehydes or ketones. The reactions are especially fast and selective in the case of substituted benzaldehydes. The reactivities of various nitrogen functional

Catalyticenantioselective conjunctive cross‐coupling between 9‐BBN borate complexes and aryl electrophiles can be accomplished with Ni salts in the presence of a chiral diamine ligand. The reactions furnish chiral 9‐BBN derivatives in an enantioselective fashion and these are converted to chiral alcohols and amines, or engaged in other stereospecific C−C bond forming reactions.

A benzylation of aldehydes using primary and secondary benzylboronic acid pinacol esters is reported. Activation of the boronic ester with s-butyllithium rendered it nucleophilic toward aldehydes. The activatednucleophile chemoselectively transfers the benzyl group over the sec-butyl group, providing excellent yields of the benzylated products. 11B NMR experiments were performed to study the mechanism
据报道,使用伯和仲苄基硼酸频哪醇酯对醛进行苄基化。与硼酸酯的活化小号丁基锂渲染它亲核朝向醛。活化的亲核试剂化学选择性地将苄基转移到仲丁基上,从而提供了极佳的苄基化产物收率。进行11 B NMR实验以研究这种转化的机理。
