The treatment of various 1,3-dihalides including the ones bearing an ester group with the titanocene(II) species produced cyclopropanes in good yields. The reaction of dihalides possessing two secondary halogens proceeded stereoselectively to afford trans-isomers as major products.
各种含酯基的1,3-二卤化物及其他1,3-二卤化物的处理方法与二茂钛(II)物种发生反应,能够以良好的产率生成环丙烷。具有两个二级卤素的二卤化物的反应立体选择性地进行,主要产物为反式异构体。
