2-benzocycloheptatriene-7-methyl ether. This sole product results from an equilibrium and not a kinetic controlled process. The reaction of benzotropenium ion with MeMgI leads to approximately an equal mixture of 7-methyl-1,2-and 7-methyl-3,4-benzocycloheptatriene. Essentially the same product ratio is derived from the reaction of 3,4-benzocycloheptatriene-7-methyl ether with MeMgI, while 1,2-benzocy
苯trop离子与甲醇钠反应仅生成1,2-苯并环庚三烯-7-甲基醚。唯一的产品来自平衡而不是动力学控制的过程。苯并trop离子与MeMgI的反应导致7-甲基-1,2-和7-甲基-3,4-苯并环庚三烯的混合物大致相等。从3,4-苯并环庚三烯-7-甲基醚与MeMgI的反应中基本上得到相同的产物比例,而1,2-苯并环庚三烯-7-甲基醚主要产生7-甲基-1,2-苯并环庚三烯。
