  摘要：

  AbstractThe rhodium(I)‐catalyzed reaction between arylboronic esters and excess 1,2‐dichloroethene selectively afforded (2‐chlorovinyl)arenes. Double arylation yielding 1,2‐diarylethenes was observed when 1,2‐dibromoethene was reacted with 2.5 equivalents of arylboronic acid.magnified image

  Chromium-catalyzed olefination of arylaldehydes with haloforms was achieved using 2,3,5,6-tetramethyl-N,N′-bis(trimethylsilyl)-1,4-dihydropyrazine (1a) as an organic reducing agent, giving β-halostyrene derivatives in a trans-selective manner. The reaction required no metal powders, such as zinc and manganese, as reductants, thereby minimizing metal-based reaction waste.

  以2,3,5,6-四甲基-N , N'-双(三甲基甲硅烷基)-1,4-二氢吡嗪( 1a )为有机还原剂,铬催化卤代芳醛烯化,得到β-卤代苯乙烯衍生物以反式选择的方式。该反应不需要锌和锰等金属粉末作为还原剂，从而最大限度地减少了金属基反应废物。

  Julia olefination between alpha-halomethyl sulfones and a variety of aldehydes afforded alkenyl halides in good to excellent yields with high E/Z stereo selectivities. Sulfones were readily prepared in two or three steps from commercially available reagents in good yields. Optimization revealed that the nature of the Z solvent, the base, and the additive were crucial to obtain the desired alkenyl halides.
