Novel 1,2-Di(2-pyrrolyl)ethenes 5 and related compounds 8 have been prepared in good yield using the Wittig reaction. Although the Horner reaction can be used for the synthesis of 1,2-di(2-thienyl)- and 1, 2-di(2-furyl)-ethenes, the procedure is not suitable as a viable route for the preparation of the corresponding dipyrrolylethenes.
新型1,2-二(2-
吡咯基)
乙烯5及相关化合物8已通过维蒂希反应以良好产率合成。尽管霍纳反应可以用于合成1,2-二(2-
噻吩基)和1,2-二(2-
呋喃基)
乙烯,但该方法不适合用于合成相应的二
吡咯乙烯。
