The historically The historically important acid reported in 1881 by Markownikoff and Krestownikoff and assigned the structure 1,3-cyclobutanedicarboxylic acid (a structure which hasnever subsequently been questioned) was shown to be 1-methyl- 1,2-cyclopropanedicarboxylic acid. The mechanism of the for­mation of the Markownikoff-Krestownikoff acid is discussed.

Spiro(3,5)nonane was prepared by methods indicativeof structure.The historically The historically important acid reported in 1881 by Markownikoff and Krestownikoff and assigned the structure 1,3-cyclobutanedicarboxylic acid (a structure which hasnever subsequently been questioned) was shown to be 1-methyl- 1,2-cyclopropanedicarboxylic acid. The mechanism of the for­mation of the Markownikoff-Krestownikoff acid is discussed.The previously unknown cis- and trans-1,3-cyclobutane­-dicarboxylic acids were synthesized. After numerous unsuc­cessful attempts the synthesis was achieved starting from pentaerythritol. The reaction between the benzylidene der­ivative of 2,2-bis(bromomethyl)-1,3-propandiol and sodiummalonic ester gave a condensation product which after hydrolysis and oxidation with nitric acid yielded 1,1,3,3-cyclobutanetetracarboxylic acid. On decarboxylation of the latter, the desired acids were obtained.
