and iron(II) salts, and mixtures of copper, chromate, and arsenate salts (CCA, a timber preservative) also promote degradation in the presence or absence of iron ions. The oxidation of 1,5-anhydrocellobiitol by oxygen in the presence of iron ions is strongly inhibited by CCA and by cetyltrimethylammonium chloride, and is accelerated by phenols and related compounds.

3-Ketosucrose (alpha-D-ribo-hexopyranosyl-3-ulose-beta-D-fructofuranoside), obtained from sucrose via microbial oxidation with Agrobacterium tumefaciens, was shown to be an appropriate and versatile synthon for regioselective syntheses. Condensation with hydroxylamine and its derivatives with allyl and benzyl groups leads to the oxime and the corresponding substituted products. By reductive amination
