我们在本文中介绍2-卤代硒基与硼酸经钯盐催化的铃木偶联反应的结果,并描述了建立以高收率制备2-芳基硒烯和2,5-二芳基硒烯的新途径。该反应在温和的条件下干净地进行,并在DME中存在Pd(OAc)2,K 2 CO 3 / H 2 O的情况下,用带有吸电子,给电子和中性取代基的芳基硼酸进行。另外,通过该方案,还通过羰基化方法从2-碘硒基苯和硼酸获得不对称的芳基酮。

2-haloselenophenes with terminalalkynes catalyzed by PdCl2(PPh3)2, under co-catalyst free conditions and establish a new procedure to prepare (2-alkynyl)-selenophenes in good yields. The reaction proceeded cleanly under mild reaction conditions and was performed with propargylic alcohols, protected propargylic alcohols, propargylic amines, as well as alkyl, and aryl alkynes, in the presence of PdCl2(PPh3)2

phthalonitrile, and the mixture was reacted with ruthenium(III) trichloride and 4-methylpyridine in the presence of 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) in refluxed 2-ethoxyethanol to give 1,3-diphenylselenophenotetraazaporphyrinato ruthenium(II) bis(4-methylpyridine) (6). The structure of 6 was determined by 1H NMR and fastatombombardmentmassspectrometry (FABMS). In the 1H NMR spectrum, the signals
