New passages
A passage about manufacturing, if any, would be useful, as would a passage about any known uses of this substance. Nolabob (talk) 15:06, 3 November 2023 (UTC)


 * Manufactured by [1+2]-Cycloaddition of dichlorocarbene to trichloroethene in a two-phase reaction with phase-transfer catalyst trimethylbenzylammoniumchloride between trichloroethene and an alcalic phase of sodium trichloroacetate. Sodium trichloroacetate is smoothly decomposed into :CCl2, CO2 and NaCl.
 * Pentachlorocyclopropane is created in moderate yield, it has a distinct "green apple" odour.
 * This molecule is of theoretical importance as a starting material for the first successful synthesis of a 'triafulvalene' Science-is-Change (talk) 20:27, 9 December 2023 (UTC)
