  Electrophilic organic selenium reagents—protonated seleninic acids as precursors for unsymmetrical aromatic selenides

  摘要：

  Arylselenylations of methylbenzenes, methoxybenzenes and thiophene were smoothly achieved with selenenium ions generated by comproportionation of 1:1 mixtures of p-toluenesulfonic acid salts of seleninic acids and the corresponding diselenides. A series of p-toluenesulfonic salts of seleninic acids were prepared by hydrogen peroxide oxidation of the corresponding diselenides in the presence of p-toluenesulfonic acid. Novel 2-(organylseleno)thiophenes were obtained by heating the protonated seleninic acids with a 50-fold excess of thiophene in glacial acetic acid. (C) 2011 Published by Elsevier Ltd.

  The use of an air‐ and moisture‐stable dinuclear PdI complex as an efficient catalyst for the formation of C(sp2)−SeR bonds is here reported. The privileged reactivity of the PdI dimer allows for the direct use of selenolates as nucleophiles in the cross‐coupling. Although previous methodologies suffer from catalyst poisoning through the formation of Pd‐ate complexes, the mechanistically distinct dinuclear

  据报道，使用空气和水分稳定的双核Pd I配合物作为形成C（sp 2）-SeR键的有效催化剂。Pd I二聚体具有优越的反应性，可在交叉偶联中直接使用硒油酸酯作为亲核试剂。尽管以前的方法会因形成Pd-盐配合物而使催化剂中毒，但在机理上截然不同的双核Pd I催化剂却克服了这一挑战。在相对温和的反应条件下，具有宽泛的官能团耐受性的各种芳基溴化物和碘化物可有效偶联。提供了力学和计算数据以支持直接的Pd I反应性。
