1,2‐Diferrocenyl‐3‐(methylthio)cyclopropenylium iodide reacts with malonic acid derivatives (diethyl malonate and malononitrile as the active methylene compounds) to give mainly the corresponding 3,4‐diferrocenyl‐2‐(methylthio)hexa‐2,4‐dienedioic acid and 2,3‐diferrocenyl‐4‐(methylthio)buta‐1,3‐diene‐1,1‐dicarboxylic acid derivatives as well as ethyl 2,3‐diferrocenyl‐4‐(methylthio)‐5‐oxocyclo‐1,3‐pentadiene‐1‐carboxylate or 2‐cyano‐3,4‐diferrocenyl‐5‐(methylthio)‐2,4‐cyclopentadien‐1‐imine. X‐ray diffraction data for diethyl (2 Z ,4 E )‐3,4‐diferrocenyl‐2‐(methylthio)hexa‐2,4‐dienedioate and 2,3‐diferrocenyl‐4‐(methylthio)buta‐1,3‐diene‐1,1‐dicarbonitrile are presented.
