An oxidation system in which iodic acid (HIO3) is used as an oxidant in the presence of N-hydroxyphthalimide (NHPI) permitted the selective hydroxylation of tertiary C-H bonds and the lactonization of carboxylic acids containing a tertiary carbon center. These reactions are operationally simple and proceed under metal-free conditions using commercially available reagents, thus offering an ideal tool for the efficient oxidation of C-H bonds at tertiary carbon centers.
Synthesis of 1,4-dioxa-2λ5-phosphorinanes by insertion of triphenylalkylidenephosphoranes into the peroxide bond of 1,2-dioxetanes: Thermolysis, hydrolysis, and wittig olefination

The reaction of the methyl-substituted 1,2-dioxetanes 1-3 with triphenylalkylidenephosphoranes 4-7 was investigated. By nucleophilic attack of the negatively charged phosphorane carbon atom at the peroxide bond of the 1,2-dioxetanes, the dipolar phosphoni

The alcoholysis of various esters of aromatic carboxylic esters with octadecanol in the presence of lead stearate was investigated by chromatographic analysis of the reaction mixtures.The reactivity of the esters was found to be strongly affected by the substitution pattern of the aromatic nucleus as well as by the structure of the alkoxy group.Electron donating substituents in a suitable position lead to a remarkable increase in reactivity compared to the unsubstituted alkyl esters. - Keywords: Mono and polycarboxylic esters; Metal salt catalysis; Kinetics; Chromatographic analysis
