  One-pot synthesis of mixed ( )-1,2-bis(organylchalcogene)-1-alkenes precursors of the novel β-organylthio vinyllithium intermediates

  摘要：

  One-pot hydrochalcogenation of 1-phenylthioacetylenes using organylselenolate and organyltellurolate anions generated by the insertions of selenium and tellurium in n-organyl lithium produced (Z)-1,2-bis(organylchalcogene)-1-alkenes. The chemical reactivity of these mixed 1,2-bis(organylchalcogene)-1-alkenes was studied by Te/Li and Se/Li stereoretentive exchanges carried out with n-butyl lithium, furnishing the new intermediate species (Z)-beta-organylthio vinyllithium anions, which were trapped with aldehydes, to give the (Z)-3-hydroxy vinyl thioethers with total control of the regio- and stereochemistry.

  铜纳米粒子通过S–S和C–H键的活化催化C–S键的形成：炔烃硫化物的简便方法

  摘要：

  摘要 通过使用二甲基亚砜作为溶剂，碱和分子氧作为绿色氧化剂，开发了一种有效的铜纳米颗粒催化无配体SC键形成的方法。这项研究为通过S–S和C–H键的双重活化生产炔基硫化物提供了一条新的催化途径。以低催化剂负载量（0.5mol％Cu）大规模合成了各种各样的炔基硫化物。这种合成方法也可以扩展到硒化物，而碲化物在没有催化剂的情况下进行类似的反应。 通过使用二甲基亚砜作为溶剂，碱和分子氧作为绿色氧化剂，开发了一种有效的铜纳米颗粒催化无配体SC键形成的方法。这项研究为通过S–S和C–H键的双重活化生产炔基硫化物提供了一条新的催化途径。以低催化剂负载量（0.5mol％Cu）大规模合成了各种各样的炔基硫化物。这种合成方法也可以扩展到硒化物，而碲化物在没有催化剂的情况下进行类似的反应。

  and selective aerobic cross-dehydrogenative coupling of terminal alkynes with thiols to construct alkynyl sulfides catalyzed by Cu(I) using molecular oxygen as the oxidant has been demonstrated under mild reaction conditions. The process is applicable to a wide range of alkynes and various thiols and is compatible with a variety of functional groups on both alkyne and thiol coupling partners.

• Regioselectivity in the reaction of tantalum-unsymmetrical acetylene complexes with carbonyl compounds. Stereoselective preparation of 1-alkenyl sulfides, .alpha.,.beta.-unsaturated esters, and amides

  Tantalum-alkyne complexes, derived by treatment of alkynes with low-valent tantalum (TaCl5 and zinc), react in situ with carbonyl compounds to give (E)-allylic alcohols stereoselectively. When unsymmetrical acetylenes are employed in the reaction, two regioisomeric allylic alcohols are produced. The regioselectivity of the reaction depends on the steric and electronic effects of the substituents on the acetylenes. For example, treatment of tantalum-alkyne complexes derived from methyl alkynyl sulfides with carbonyl compounds yields (E)-3-hydroxy-1-propenyl methyl sulfides in a regioselective manner. Tantalum-alkyne complexes derived from acetylenic esters react with carbonyl compounds regioselectively at the alpha-position of the esters to give Z-isomers of trisubstituted alpha,beta-unsaturated esters. In contrast, tantalum-alkyne complexes derived from acetylenic amides react with carbonyl compounds predominantly at the beta-position of the amides. The regioselectivity of the reaction between acetylenic amides and aldehydes, however, cannot be explained solely in terms of the steric and electronic effects of the substituents. Strong coordination of the amide group to the tantalum center could also be responsible for the observed selectivity, which is opposite to that observed with tantalum-acetylenic ester complexes.
