Experiment 12 – The Magtrieve TM Oxidation of 4-Chlorobenzyl Alcohol, A Solvent-Free Reaction Introduction: Magtrieve, a recyclable, selective chromium oxidant, is of great importance in the oxidation of primary alcohols for it does not over-oxidize the alcohol of interest to carboxylic acid and can be magnetically retrieved easily 1 . Chromium dioxide was first reported as a selective oxidant with properties superior to Manganese (IV) Oxide by researchers at DuPont in the year 1997 2 . In light of understanding Chromium and its compounds’ environmental impacts, Magtrieve and other chromium reagents were evaluated by Kirklin in his peer-reviewed journal article 3 . In this experiment, 4-Chlorobenzaldehyde 3 was formed by the Magtrieve TM 2 oxidation of 4-Chlorobenzyl alcohol 1 (Scheme 1). As a result of this reaction, the reduced chromium (III) product 10 was also produced, in twice the quantity of that of 4-Chlorobenzaldehyde 3 formed.
