A novel C–H oxidation of cyclic ethers and amines to the corresponding lactones and lactams was developed using a DIB/TBHP protocol. The reaction is mild and no metallic reagent is involved. In addition, study shows that the electronic properties of the substituents could affect the selectivity of oxidation.

A mild and efficient catalytic method for the benzylic oxidation of alkyl arenes to the corresponding tert. butyl aryl peroxides is described using a catalytic amount of reusable solid, Ru-III-exchanged Montmorillonite K10 and 70% tert. butyl hydroperoxide (TBHP) as oxidant.

monothioacetalization and allylation of hemiacetals. The reactions, which take place undermildconditions and at low catalyst loadings, can be conducted using hemiacetals, the corresponding O-silyl ethers, and, in some cases, the acetal dimers. Aldehydes react under similar conditions to furnish good yields of dithioacetals. Reactions of hemiacetals with nitrogen nucleophiles are unsuccessful. 1,2-Dioxolan-3-ols
