1,6-Bis(ferrocenyl)-1,3,5-hexatriyne: Novel preparation and structural study

摘要

1,6-Bis(ferrocenyl)-1,3,5-hexatriyne (Fc(C C)(3)Fc) was prepared from the reaction between 3-(dibromomethylidene)1,5- bis(ferrocenyl)penta-1,4-diyne and BuLi Via an alkynyl migration in a Vinylidene carbenoid mechanism. Both the title compound and its precusors were thoroughly characterized, and the electronic couplings between two ferrocenyl units were assessed with voltammetric techniques.
