Alkylation of ferrocene with tetrachlorocyclopropene in the presence of AlCl3 followed by aqueous workup affords 2,3-diferrocenylcyclopropenone in high yield.

Abstract

Alkylation of ferrocene with tetrachlorocyclopropene in the presence of AlCl3 followed by aqueous workup affords 2,3-diferrocenylcyclopropenone in high yield. We have studied some of this ketone's chemical transformations and electrochemical properties. 2,3-Diferrocenylcyclopropenone withstands thermolysis; it is stable in an acidic medium; the action of tetrafluoroboric acid-diethyl ether results in the formation of diferrocenyl(hydroxy)cyclopropenylium tetrafluoroborate; nucleophiles, including methyllithium and lithium aluminum hydride, react regioselectively with the three-membered ring by opening it to form the respective substituted cis-diferrocenylethenes. We present data from X-ray diffraction analyses of 2,3-diferrocenylcyclopropenone, isopropyl cis-2,3-diferrocenylacrylate, and cis-3,4-diferrocenyl-2-methylbut-3-en-2-ol. © Wiley-VCH Verlag GmbH & Co.
