Abstract

Abstract A new complex [RuCl2(dppf)(PN)] 1 (dppf = 1,1′-bis(diphenylphosphino) ferrocene; PN = (2-diphenylphosphino)benzenamine) has been synthesized and characterized. Its structure was determined by single-crystal X-ray diffraction. An efficient 1/Pd salt-cocatalyzed three-component oxidation/cyclization/Suzuki reaction for the synthesis of 2-pyridinyl-6-arylquinolines from 2-acetylpyridine, (2-amino-5-bromophenyl)methanol, and arylboronic acids has been developed.

[RuCl2(dppf)(PN)]/ pd共催化三组分合成2-吡啶基-6-芳基喹啉
一种新型配合物[RuCl2(dppf)(PN)] 1 (dppf = 1,1′-双(二苯基膦)二茂铁;合成了PN =(2-二苯基膦)苯胺并对其进行了表征。用单晶x射线衍射测定了其结构。以2-乙酰吡啶、(2-氨基-5-溴苯基)甲醇和芳基硼酸为原料,采用1/Pd盐催化三组分氧化/环化/Suzuki反应制备了2-吡啶基-6-芳基喹啉。
