A colorless solid, the compound is a reagent used to prepare acetylene derivatives.[1] It is prepared by addition of dichlorocarbene to tetrachloroethylene.[2]The compound is used to prepare arylpropiolic acids: C3Cl4 + ArH + 2 H2O → ArC2CO2H + 4 HCl Under some circumstances, diarylation occurs, giving diarylcyclopropenones, which decarbonylate to give diarylacetylenes. These reactions are thought to proceed via the intermediacy of trichlorocyclopropenium electrophile (C3Cl3+).
