A facile and efficient method for monoketalization of 1,4-cyclohexanedione. Babler, James H.; Spina, Kenneth P. (Dep. Chem., Loyola Univ. Chicago, Chicago, IL 60626, USA). Synth. Commun., 14(1), 39-44 (English) 1984. CODEN: SYNCAV. ISSN: 0039-7911. DOCUMENT TYPE: Journal CA Section: 24 (Alicyclic Compounds) Monoketal I was obtained selectively when the reaction mixt. was continuously extd. by hexane. 1,4-Cyclohexanedione was dissolved in aq. H2SO4 contg. 126-30-7 and 29280-23-7 which are cas registry numbers of substances are two of reagents here. HOCH2CMe2CH2OH, NaHCO3 was introduced to prevent bisketalization, and the soln. was continuously extd. with hexane to remove I. .

DOCUMENT TYPE: Journal CA Section: 79 (Inorganic Analytical Chemistry) Section cross-reference(s): 22, 77 A new NMR expt. is reported, where the spectrometer is triggered using the output from a combination redox electrode. This technique was used to probe redox oscillations in the 1,4-cyclohexanedione-acid-bromate reaction. Manganese(III) acetate or manganese(II) sulfate was used as the catalyst, and the periodic change in concn. of Mn2+/Mn3+ ions was detd. as a function of redox potential. The concn. of Mn3+ ions was at a max. at high redox potential and at a min. at low redox potential. Also, redox potentials not be dominated by the Mn2+/Mn3+ couple. .
