  摘要：

  AbstractWe present (homepage: www.ufsm.br) herein the application of copper nanoparticles/diorganyl dichalcogenides to promote the synthesis of 2‐(organochalcogen)thiazoles via direct carbon‐hydrogen bond activation in thiazoles. A systematic study of the catalytic system revealed that the presence and amount of base played an essential role in this reaction. The results revealed that electron‐donating and electron‐withdrawing substituents, in the aromatic ring bonded to the chalcogen atom of diorganyl dichalcogenides, required one equiv. of base, while when neutral substituents were present two equiv. of base were needed to deliver the products in similar yields.magnified image

  Alumina-supported Cu(II) efficiently catalyzes selenylation of aryl iodides and aryl bromides by diaryl, dialkyl, and diheteroaryl diselenides in water and PEG-600, respectively, leading to a general route toward synthesis of unsymmetrical diaryl, aryl–alkyl, aryl–heteroaryl, and diheteroaryl selenides. A sequential reaction of bromoiodobenzene with one diaryl/diheteroaryl/dialkyl diselenide in water and another

  氧化铝负载的Cu（II）分别在水和PEG-600中有效地催化二芳基，二烷基和二杂芳基二硒化物对芳基碘化物和芳基溴化物的硒化，从而通向合成不对称二芳基，芳基-烷基，芳基-杂芳基和二杂芳基硒化物。在第二步中，溴碘代苯与一种二芳基/二杂芳基/二烷基二硒化物和另一种二芳基/二杂芳基/二烷基二硒化物在水中的顺序反应在第二步中产生不对称的二芳基，二杂芳基或芳基-烷基双-硒基苯。通过该方案，可以高收率获得功能化的有机单硒化物和双硒化物的文库，包括一个有效的生物活性分子和一对生物活性硒化物的类似物。反应是化学选择性的和高产率的。铜铝2O 3催化剂可循环使用七次，而不会损失任何活性。
• Visible Light Photocatalyzed Direct Conversion of Aryl-/Heteroarylamines to Selenides at Room Temperature

  日期：2014.3.21

  A novel strategy for the direct conversion of aryl- and heteroarylamines to selenides has been developed via diazotization of amines with tert-butyl nitrite in neutral medium followed by reaction with diaryl/diheteroaryl/dialkyl diselenides in one pot under photocatalysis at room temperature in the absence of any metal. This reaction is also applied for the synthesis of tellurides. The selenylation of heteroarylamine by this protocol is of much significance because of the difficulty in diazotization of these molecules by a standard diazotization method in acid medium.
