| abstract | A cyclopropane ring compound is produced electrolytically at an anode immersed in a solution of an aliphatic carboxylic acid having at least 4 carbons, with or without an alkali metal salt of a carboxylic acid, preferably formed in situ from the same free acid with a caustic alkali such as KOH. For example, an aqueous electrolyte solution containing n-butanoic acid, partly neutralized with KOH, yields an off-gas containing cyclopropane, propene, hydrogen, CO2 and CO, which may be collected by water displacement. If the solution contains instead n-pentanoic acid or 2- or 3-methylbutanoic acid, methylcyclopropane with all the butene isomers, together with some cyclopropane, propene, ethylene, butane, are obtained at the anode, the cyclopropanes being separated by fractionation using a reflux condenser and extracted with ether. Non-aqueous solutions may be used containing methanol, ethylene glycol, acetonitrile or dimethyl sulphoxide. The anode may be of graphite, gold, nickel or brown lead oxide, and the cathode of graphite, copper, stainless steel, platinum, silver, nickel or lead. The current density is preferably 0.01-0.5 amp/sq cm. |
