C2H 6 • CO' CH( CH3) • CO2H -> C2H6 • CO. CH2 • CH3; and by the action of zinc alkyls on acid chlorides (M. Freund, Ann., 1861, 118, p. 1), 2CH3COCl+ZnCH3)2=ZnC12+2CH3•CO•CH3. In the last reaction complex addition products are formed, and must be quickly decomposed by water, otherwise tertiary alcohols are produced (A. M. Butlerow, Jahresb., 1864, p. 496; Ann. 1867, 144, p. 1). They may also be prepared by the decom- position of ketone chlorides with water; by the oxidation of the tertiary hydroxyacids; by the hydrolysis of the ketonic acids or their esters with dilute alkalis or baryta. water (see AcETO-ACETIC ESTER); by the hydrolysis of alkyl derivatives of acetone dicarboxylic acid, H02C•CH2•CO•CHR•CO2H; and by the action of the Grignard reagent on nitriles (E. Blaise, Comptes rendus, 1901, 132, p. 38),
