Abstract:

An efficient method for the oxidation of alcohols is presented. Using catalytic amounts of manganese porphyrin [Mn(TPP)CN] in combination with (diacetoxyiodo)benzene (PhI(OAc)2) allows the conversion of benzylic and primary aliphatic and aromatic alcohols into the corresponding aldehydes, and secondary alcohols to ketones as the sole products. This method provides a cost-effective and environmentally friendly oxidation procedure due to the utilisation of less toxic PhI(OAc)2 and biologically relevant manganese porphyrins. The amounts of the products (%) and the selectivities are very dependent upon the nature of the metalloporphyrin catalysts and also upon the electronic and steric properties of the starting alcohols.

The Journal of Chemical Research is a monthly journal which has a broad international authorship and publishes research papers and reviews in all branches of experimental chemistry.
Recent papers have described new synthetic methods, new heterocyclic compounds, new natural products, and the inorganic chemistry of metal complexes. Now in its 34th year, the Journal of Chemical Research was established in 1977 as a joint venture by the British, French and German chemical societies and maintains the high standards set by the founding societies. Each paper is independently peer reviewed and only carefully evaluated contributions are accepted.
