WebFor cyclopropane and cyclobutane, the strain energy is about 110 kJ/mol. Cyclobutane can enter a “puckered” formation that slightly relieves some torsional strain. Cyclopentane, which is non-planar can remove some of the strain and has only about 25 kJ/mol of strain. Cyclopropane was discovered in 1881 by August Freund, who also proposed the correct structure for the substance in his first paper. Freund treated 1,3-dibromopropane with sodium, causing an intramolecular Wurtz reaction leading directly to cyclopropane. The yield of the reaction was improved by Gustavson in 1887 with the use of zinc instead of sodium. Cyclopropane had no commercial application until Henderson and Lucas discovered its anaesthetic properties in 1929…
