General description

Tetrachlorocyclopropene undergoes electrochemical reductive tert-butyldimethylsilylation to yield 1,2,3-tris(tert-butyldimethylsilyl)cyclopropene. It undergoes alkylation reaction with ferrocene in dichloromethane and AlCl3 to yield 2,3-diferrocenylcyclopropenone.

Application

Tetrachlorocyclopropene was used to prepare starting reagent for synthesis of 3,3-diethyl-and 3,3-dibenzyl-1,2-diferrocenylcyclopropenes.

Electrochemical reductive tert-butyldimethylsilylation of tetrachlorocyclopropene to 1,2,3-tris(tert-butyldimethylsilyl)cyclopropene, a potential strained precursor for Diels-Alder and related cycloaddition reactions, is described. By hydride abstraction with nitrosonium tetrafluoroborate, 1,2,3-tris(tert-butyldimethylsilyl)cyclopropene is ionized quantitatively to Hückeloid 2pi aromatic tris(tert-butyldimethylsilyl)cyclopropenium tetrafluoroborate.
