A linear codimerization of 2-norbornenes with acrylic compounds such as acrylates and an acrylamide proceeded efficiently by ruthenium catalyst systems, RuCl3(tpy)/Zn (tpy = 2,2‘:6‘,2‘ ‘-terpyridine) or [RuCl2(C6H6)]2/Zn in a primary or secondary alcoholic solvent, to afford the corresponding exo-trans-2-norbornylacrylates as major products regio- and stereoselectively along with a small amount of
通过钌催化剂体系,RuCl 3(tpy)/ Zn(tpy = 2,2':6',2''-叔吡啶)或[RuCl 2(C 6 H 6)] 2 / Zn在伯或仲醇溶剂中,以少量和顺式异构体的形式选择性和立体选择性地提供相应的外反式-2-降冰片基丙烯酸酯作为主要产物。2,5-降冰片二烯与丙烯酸甲酯的反应也产生了线性外-反式共聚二聚体,通过向RuCl 3中加入三芳基膦有效地催化了该反应。(tpy)/ Zn催化剂体系。
