The methyltrioxorhenium(MTO)-catalyzed oxidation of silanes to silanols and the epoxidation of various olefins by aqueous 85% H2O2 proceed in high yields and excellent product selectivities (no disiloxanes, diols) in the presence of the zeolite NaY. The oxidative species is located inside the 12- A supercages. This prevents the bimolecular condensation of the silanol to disiloxane by steric means and the Lewis-acid assisted hydrolysis of the epoxide to the diol.

Anodic oxidation of tricyclene (1a) in acetic acid containing triethylamine, followed by hydrolysis, provides a facile and efficient synthesis of exo-5,5-dimethyl-6-methylenebicycloheptan-2-ol (2a), named "nojigiku alcohol", which was isolated from the essential oil of chrysanthemum japonese.Furthermore, a method for large-scale production of 2a starting from the readily available impure starting tricyclene (1a) has been developed by appropriate selection of reaction conditions.Similar electrooxidation of the related naturally occurring polycyclic methylcyclopropanes, cyclofenchene (1b) and longicyclene (1c), followed by hydrolysis also brought about stereo- and regioselective cleavage of carbon-carbon bonds of the cyclopropane rings to give the corresponding homoallylic alcohols 2b,c in good yields.
