Abstract
Abstract Monoalkenylferrocenes were prepared from 1,1′‐diacetylferrocene and appropriate benzyl bromides by the promotion of samarium diiodide. A practical method for preparation of both symmetric and unsymmetric dialkenylferrocenes was also explored. The reactions were stereoselective to give only ( E ) double bonds. The unsymmetric dialkenylferrocene bearing electron‐donating substituent (e.g. methoxy group) and electron‐withdrawing substituent (e.g. cyano group) on different phenyl rings likely exhibits a large nonlinear optical property.
