efficient and solvent-free method for the one-pot synthesis of allylic esters via dehydrogenation of unactivated alkanes and subsequent oxidative cross coupling with different substituted carboxylic acids. A simple, well defined and air stable Cu(II)-complex, [Cu(MeTAA)], featuring a tetraaza-macrocyclic ligand (tetramethyltetraaza[14]annulene (MeTAA)) is used as the catalyst. A wide variety of substituted
摘要在这里,我们报告了一种通用,有效且无溶剂的方法,该方法通过未活化的烷烃的脱氢反应以及随后与不同取代的羧酸的氧化交叉偶合一锅合成烯丙基酯。一种简单,定义明确且空气稳定的Cu(II)络合物[Cu(MeTAA)]以四氮杂-大环配体(四甲基四氮杂[14]环戊烯(MeTAA))为催化剂。从容易获得的起始原料开始,高收率地合成了各种各样的取代的烯丙基酯。进行对照反应以了解反应顺序和合理的机理。
