Highly Strained, Ring-Tilted [1]Ferrocenophanes Containing Group 16 Elements in the Bridge: Synthesis, Structures, and Ring-Opening Oligomerization and Polymerization of [1]Thia- and [1]Selenaferrocenophanes

摘要

Cyclic voltammetric studies of 13 showed the presence of two reversible oxidation waves with a redox coupling △E=ca. 0.32 V, which is consistent with the presence of significantly stronger M...M interactions compared to those present in other ring-opened poly (ferrocences) derived from [1]ferrocenophanes.
