A method of preparing a 2,6 disubstituted anilines includes, reacting a 2-amino isophthalic acid diester with sufficient Grignard reagent R.sub.2CH.sub.2MgX to form the corresponding diol product, dehydrating the diol product to the corresponding dialkene; and hydrogenating the diol product to form the corresponding aniline. The 2,6 disubstituted anilines can be used to produce N-Heterocyclic Carbenes (NHCs). The NHCs can find application in various fields such as organic synthesis, catalysis and macromolecular chemistry. Palladium catalysts containing the NHCs are also described.

Disclosed are methods for separating, recovering, and purifying cannabidiolic acid (CBDA) salts from an organic solvent solution comprising a mixture of cannabinoids. The methods comprise solubilizing the mixture of cannabinoids in C5-C7 hydrocarbon solvents, adding thereto a selected amine to thereby precipitate a CBDA-amine salt therefrom, dissolving the recovered CBDA-amine salt in a selected solvent and then adding thereto a selected antisolvent to thereby recrystallize a purified CBDA-amine salt therefrom. The recrystallized CBDA-amine salt may be decarboxylated to form a mixture of cannabidiol (CBD) and amine. The CBD amine mixture may be acidified to separate the amine from CBD. Also disclosed are CBDA-amine salts produced with certain amines selected from groups of secondary amines, tertiary amines, diamines, amino alcohols, amino ethers, and highly basic amines.
