1896 Chem. News 10 Jan. 23/2 These researches consist of papers on the ‘History of Bibromsebacinic Acids’, by Ad. Claus, and on ‘Tautomery’ and ‘Desmotropy’ by the same chemist.
1899 E. F. Smith tr. V. von Richter Org. Chem. (ed. 3) I. 55 Laar..assumes that such compounds consist of a mixture of structural isomerides, in that an easily mobile hydrogen atom oscillates between two positions in equilibrio, and thereby the entire complex becomes mobile. He designates the phenomenon as tautomery.
1957 U.S. Patent 2,789,937 1 Another theory found by Arndt, based upon the application of the chromone–coumarin tautomery.
2004 Jrnl. Agric. & Food Chem. 52 1266/1 Keto–enol tautomery most probably determines the rate of the overall conversion.
