Fatty Alcohols Through Hydroxylation of Symmetrical Alkenes with Selenium Dioxide/tert.-Butylhydroperoxide

Several symmetrical alkenes were reacted with the selenium dioxide/tert.-butylhydroperoxide system to give three hydroxylated products each.These products were those of allylic mono- and dihydroxylation (meso and threo dihydroxy compounds) of the double bond.Some dihydroxy products were hydrogenated to give saturated 1,4-diols.The compounds were characterized by nuclear magnetic resonance.The products have potential for application in commercial products, such as biodiesel, lubricants, greases, and cosmetics. - Keywords: Hydroxylation; nuclear magnetic resonance; selenium dioxide; symmetrical alkene, tert.-butylhydroperoxide.
Decane autoxidation: Precursors of gamma lactones and other minor products

Autoxidation of decane produces the following minor products in decreasing yields, viz. 2,5-, 3,6- and 4,7-decanediones and diols. Addition of 3-decanone to a decane autoxidation enhances the production of octanal, heptanal, octanoic and heptanoic acids. 3-Decanol initially inhibits the autoxidation reaction prior to being oxidized to 3-decanone. γ-Octanoic and γ-heptanoic lactone formation in the autoxidation of decane is promoted by the addition of 3- and 4-decyl hydroperoxides, respectively. These lactones are formed when tert-butoxy radicals react with 3,6- and 4,7-decane diols in the presence of oxygen. The nature of the intermediates in the formation of the minor products and the inhibition by alcohols are discussed.
