Reductive metalation of alkali metals of hydrocarbons containing labile protons can be accompanied by proton transfer from the hydrocarbon to the derived radical anion and/or dianion. The extent of this reaction as a function of reaction conditions has been studied with trans-1,2-diphenylpropene (I). Three alkali metals, Li, Na and K, and two solvents, diethyl ether (DEE) and tetrahydrofuran (THF)
含有不稳定质子的烃的碱金属的还原金属化可伴随有质子从烃向衍生的自由基阴离子和/或二价阴离子的转移。已经用反式-1,2-二苯丙烯(Ⅰ)研究了该反应程度随反应条件的变化。检查了三种碱金属Li,Na和K,以及两种溶剂二乙醚(DEE)和四氢呋喃(THF)。
