✦ Synopsis

Many metal nitrates, especially zinc(I1) and copper(I1) nitrates, supported on silica gel, oxidized secondary and benzylic alcohols to the corresponding ketones and aldehydes efficiently. The supported reagent technique has received increasing attention in recent years.l As one oxidizng reagent of alcohol to ketone and aldehyde with metal nitrato complexes, Laszlo and his co-workers reported on appreciably unstable Fe(II1) nitrate impregnated on K 10 bentnite clay.2 We report here that some metal nitrates supported on silica gel oxidize secondary and benzylic alcohols in quite an easy operation. The results are shown in Table 1. The oxidizing >C H-OH M CN031n-Si 02 3 ;c=o

## Abstract Twelve thiols were readily oxidized to the corresponding disulfides by means of four metal nitrates supported on TAFF, a bentonitic clay, under mild conditions. However, in some cases, thioethers and other interesting by‐products were detected. Some of the disulfides showed antimicotica

Preparation of hexadecyl silica supported cupric nitrate is described. This oxidant, in carbon tetrachloride, oxidizes alcohols to their corresponding carbonyl compounds. It oxidizes primary alcohols in the presence of secondary alcohols with absolute chemoselectivity in high yields.
