A method for oxidative cleavage of a compound with an unsaturated double bond is provided. The method includes the steps of: (A) providing a compound (I) with an unsaturated double bond, a trifluoromethyl-containing reagent, and a catalyst; ##STR00001## wherein, the catalyst is represented by Formula (II):
M(O).sub.mL.sup.1.sub.yL.sup.2.sub.z  (II); wherein, M, L.sup.1, L.sup.2, m, y, z, R.sub.1, R.sub.2 and R.sub.3 are defined in the specification; and (B) mixing the compound with an unsaturated double bond and the trifluoromethyl-containing reagent to perform an oxidative cleavage of the compound with the unsaturated double bond by using the catalyst in air or under oxygen atmosphere condition to obtain a compound represented by Formula (III): ##STR00002##

The present invention describes a process to isomerize industrial hemp derived Cannabidiol (CBD) to a pure Δ8-tetrahydrocannabinol (Δ8-THC) extract. This procedure will produce Δ8-tetrahydrocannabinol that is essentially free from any detectable levels of Δ9-tetrahydrocannabinol (Δ9-THC). Included in this filing are methods and processes to scale the reaction from the lab to process to large scale manufacturing. Additionally, the resulting extract from said methods and processes consists of higher purity than previously reported in the art and greater efficiency compared to prior art.
