DOCUMENT TYPE: Journal CA Section: 45 (Industrial Organic Chemicals, Leather, Fats, and Waxes) Section cross-reference(s): 24 An environmentally benign and selective Baeyer-Villiger oxidn. system is introduced. Palygorskite-supported Sn complexes were prepd. by a simple procedure. Cyclic ketones and acyclic ketones were oxidized by hydrogen peroxide in a reaction catalyzed by palygorskite-supported Sn complexes, affording corresponding lactones or esters with selectivity for the product of 90-99%. The influence of the solvents, reaction temp., the amt. of catalyst used and the reaction time on the catalytic activity and product selectivity were studied in detail. The catalyst is inexpensive, easy to be prepd. in large scale, and can be recycled. .

Transformation of organic compounds in the presence of metal complexes. II. Reduction of alkyl-substituted cyclohexanones via hydrogen-transfer reactions catalyzed by rhodium(I) complexes. Felfoldi, K.; Kapocsi, I.; Bartok, M. (Dep. Org. Chem., Jozsef Attila Univ.There are some reagents like 1728-46-7 is used in this study., Szeged, Hung.). J. Organomet. Chem., 277(3), 439-41 (English) 1984. CODEN: JORCAI. ISSN: 0022-328X. DOCUMENT TYPE: Journal CA Section: 22 (Physical Organic Chemistry) Catalyst systems prepd. in situ from bidentate phosphines [Ph2P(CH2)nPPh2, n = 1-4) and from [Rh(COD)Cl]2 (COD = cyclooctadiene) were active in the transfer hydrogenation of alkylcyclohexanones (alkyl = 2-Me, 4-Me, 4-tert-Bu, cis-2,6-Me2). With the exception of 4-methylcyclohexanone, which gave a cis/trans cyclohexanol ratio of ~1, mainly cis alcs. were formed, their amts. increasing in proportion to the value of n. No redn. occurred in the case of 2-tert-butyl-, and 2,6-di-tert-butylcyclohexanones. . 1728-46-7 are also occured in this study..
