Modified Pickering Catalysis: Green Transfer Hydrogenation of the Tri-substituted Olefin of Tetrahydocannabinol

Green transfer hydrogenation of the trisubstituted olefin within the tetrahydrocannabinol scaffold, has been performed using minimal amount of organic solvent in water, on the basis of a modified Pickering catalysis, with greater selectivity over standard industrial conditions with decreased reaction times under ambient conditions. Examples of various solvents, surfactants, and observation of europium in the selectivity of the hydrogenated products are given.
