The Magtrieve Oxidation of 4-Chlorobenzyl Alcohol Purpose : The purpose of this experiment was to oxidize 4-chlorobenzyl alcohol using Magtrieve and therefore carrying out a reaction without the use of solvent. This oxidant is one that is recyclable and does not have the disadvantages of other harmful reactants, which leads to safer and “greener” experimentation. Procedure : The procedure involves the addition of 700 mg of Magtrieve as an oxidation reagent to 1 mmol 4-chlorobenzyl alcohol in a 30 ml beaker closed off with a watch glass. The temperature of the reaction was kept under 110C. The product of the first crop is scraped off the watch glass and weighed before a second crop is retrieved. Chromatography of the reaction was performed with a TLC plate developed in 60:40 hexane:ethyl acetate and visualized with UV and iodine. Discussion : Pyridium Chlorochromate (PCC) is a chromium-based oxidation reagent prepared by dissolving chromium trioxide in hydrochloric acid and adding pyridine. In this 1975 report, PCC is
