Summary
The free radical oxidation of Δ1 and Δ6-tetrahydrocannabinol has been examined by spin trapping techniques and intermediates that would lead to cannabinol have been trapped. The 1st step in the oxidation of Δ1-THC involves the removal of 3-H, while for Δ6-THC, either 2-H or 5-H. Intermediates were isolated which could be pyrolysed to the diene and cannabinol.
