[reaction: see text] Oxidation of alcohols to aldehydes and ketones has been studied in high yields using atmospheric oxygen and a catalytic amount of V2O5 in toluene under heating (ca. 100 degrees C). Secondary alcohols can be chemoselectively converted into ketones in the presence of primary hydroxy groups.

2,2,2-Trichloroethoxycarbonyl azide (TrocN 3 ) is an effective nitrene source for cobalt(II)-catalyzed intermolecular nitrene insertion of C-H bonds. Among different metalloporphyrins studied, Co(II)-(TPP) was shown to be a competent catalyst for the selective amination of various benzylic C-H bonds under mild conditions without the need of other reagents or additives, forming the desired Trocprotected amines in moderate to high yields with nitrogen gas as the only byproduct.
