祝贺邵黎雄老师指导的研究生肖正康在organic letter上发表学术论文-威尼斯人888nhc-pd(ii)-im complex 1 was found to be an effective catalyst for the α-arylation of unprotected oxindoles with aryl chlorides to give products 4 in 44–98% yields under a n2 atmosphere. furthermore, if the reactions were first performed under conditions identical to those for the α-arylation reaction for 12 h and then exposed to air for another 3 h, 3-aryl-3-hydroxy-2-oxindoles 5 can be obtained in 49–84% yields in a one-pot procedure. | |||
