Pyrrole Studies; 34¹. Synthesis of 1,2-Di(2-pyrrolyl)ethenes and Related Compounds

Abstract

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.
