Double Bond Stabilizing Abilities of Formyl, Carbo-tert-butoxy, and Carbomethoxy Substituents

Equilibrium constants for reactions of the type trans-MeCH=CHCH2COX trans-EtCH=CHCOX, where X is H, OMe, and O-t-Bu, have been determined in tert-butyl alcohol solution at various temperatures by using basic catalysts.These equilibrium constants for formation of the conjugated isomer, extrapolated to 25 deg C, are 24, 4.9, and 5.1 for the aldehyde, methyl ester, and tert-butyl ester, respectively.Possible explanations for the relative magnitudes of these equilibrium constants are discussed.

Chromium-Catalyzed Production of Diols From Olefins

Processes for converting an olefin reactant into a diol compound are disclosed, and these processes include the steps of contacting the olefin reactant and a supported chromium catalyst comprising chromium in a hexavalent oxidation state to reduce at least a portion of the supported chromium catalyst to form a reduced chromium catalyst, and hydrolyzing the reduced chromium catalyst to form a reaction product comprising the diol compound. While being contacted, the olefin reactant and the supported chromium catalyst can be irradiated with a light beam at a wavelength in the UV-visible spectrum. Optionally, these processes can further comprise a step of calcining at least a portion of the reduced chromium catalyst to regenerate the supported chromium catalyst.

Highly practical and efficient preparation of aldehydes and ketones from aerobic oxidation of alcohols with an inorganic-ligand supported iodine catalyst

Herein, we divulge an efficient protocol for aerobic oxidation of alcohols with an inorganic-ligand supported iodine catalyst, (NH4)5[IMo6O24]. The catalyst system is compatible with a wide range of groups and exhibits high selectivity, and shows excellent stability and reusability, thus serving as a potentially greener alternative to the classical transformations.
