Dinitrogen oxide was employed as a clean oxidant for various oxidations in the presence of a catalytic amount of dioxoruthenium tetramesitylporphyrin complex (Ru(tmp)(O)2). A variety of olefins, secondary alcohols, and benzyl alcohols were smoothly oxidized to the corresponding epoxides, ketones, and aldehydes in high yields. In the oxidation of 9,10-dihydroanthracene derivatives, the competitive reactions affording anthraquinones and anthracenes could be regulated by the reaction conditions. At a high temperature (200°C), anthraquinones were selectively produced, while the anthracenes were selectively produced by the addition of sulfuric acid.

The combination of Ir, which has a strong affinity for carbonyl groups, with an acid H-β zeolite as a support and promotor, provides an effective catalyst for the chemoselective hydrogenation of α,β-unsaturated aldehydes and ketones to the corresponding allylic alcohols. Steroidal enones are suitable substrates for this transformation (see scheme). R = CH (Me)(CH2)3CH(Me)2.
