strained CC double bonds in bicyclo[2.2.1]hept-2-ene and bicyclo[2.2.1]heptadiene and to 1,3-alkadienes if the reaction of the etherate of (I) with olefin is carried out in an apolar reaction medium between 60 and 130°. Reaction products of the mono-olefins are the 1,1-adducts; derivatives of divinylcyclohexane are formed with butadiene as 1,3-adducts. With bicyclo[2.2.1]heptadiene the addition of the magnesium
苄基氯化镁(I)加成至乙烯和1-烯烃,双环[2.2.1]庚-2-烯和双环[2.2.1]庚二烯中的应变CC双键以及1,3-链二烯(I)的醚化物与烯烃的反应在60至130°之间的非极性反应介质中进行。单烯烃的反应产物是1,1-加合物。二乙烯基环己烷的衍生物与丁二烯形成1,3加合物。用双环[2.2.1]庚二烯添加镁化合物,然后将分子内Mg = C加成至第二个双键中,形成2-苄基三环[2.2.1.0 1 ]庚-3-基氯化镁。
