  Synthesis of α,β-Unsaturated Aldehydes and Methyl Carboxylic Esters from 2-Acetylenic Phenyl Sulfides.

  摘要：

  2-Alkynylthio benzenes were reduced to 2-Alkenylthio benzenes with diisobutyl aluminum hydride. Mono chlorination of these compounds with sulfuryl chloride and pyridine followed by hydrolysis, in the presence of Cu-II salts, gave alpha,beta-unsaturated aldehydes.2-Alkynylthio benzenes were converted into 2-Alkynyl 1,1-bis thiobenzenes by monochlorination with sulfuryl chloride and pyridine followed by treatment with thiophenol and triethylamine. These substances were then converted to alpha,beta-unsaturated methyl carboxylic esters by way of isomerization with sodium methoxide to the corresponding allene and treatment with hydrochloric acid and methanolysis in the presence of iodine.

• Preparation and Reaction of γ-Ethoxy and (Phenylthio)allenylstannanes

  γ-Ethoxyallenylstannane was obtained by the reaction of 2-ethoxy-3-alkynenitrile or 1-ethoxy-1-(phenylthio)-2-alkyne with tributylstannyllithium in good yield. The reaction of 1,1-bis-(phenylthio)-2-alkyne with tributylstannylcopper(I) reagent gave γ-(phenylthio)allenylstannane which, in turn, was treated with acetal in the presence of TiCl4, to afford the propargyl sulfide derivative predominantly.

  γ-乙氧基乙炔基锡烷是通过2-乙氧基-3-炔腈或1-乙氧基-1-(苯硫基)-2-炔与三丁基锡锂反应得到的，产率良好。1,1-双-(苯硫基)-2-炔与三丁基锡铜(I)试剂反应生成γ-(苯硫基)乙炔基锡烷，后者在TiCl4存在下与缩醛反应，主要生成炔丙基硫醚衍生物。
• Preparation of alkynylcyclopropanes by the titanocene(II)-promoted reaction of 1,1-bis(phenylthio)-2-alkynes with 1-alkenes

  日期：2002.8

  The desulfurization of 1,1-bis(phenylthio)-2-alkynes with the titanocene(II) species Cp2Ti[P(OEt)3]2 in the presence of 1-alkenes produced 1-alkyn-1-ylcyclopropanes in good yields.

  在1-烯烃存在下，用钛茂（II）物种Cp 2 Ti [P（OEt）3 ] 2对1,1-双（苯硫基）-2-炔烃进行脱硫，生成了1-炔基-1-基环丙烷产量。
