The invention describes a high yield process that utilizes selective catalysts for the conversion of abundant, naturally occurring terpenes into bisphenols, and their derivative bis(cyanate)esters, resins, and polymers. High performance, low-cost composite materials with low moisture uptake and high glass transition temperatures suitable for aerospace applications can be prepared from these renewable starting materials.

Provided is a process for recovery of a functionalized compound reaction product comprising contacting (i) an oxidizing electrophile comprising a main group element, and (ii) a compound comprising at least one CH bond, in an acidic medium to form a reaction milieu comprising a functionalized compound reaction product, contacting the reaction milieu with a water-immicible organic solvent, separating the water-immiscible organic solvent from the reaction milieu, wherein the functionalized compound reaction product is dissolved in the water-immiscible organic solvent, and separating the functionalized compound reaction product and the water-immiscible organic solvent. The water-immiscible extraction solvent can be the same compound as the compound comprising as least one CH bond, for example, propane or n-butane.

Oxidizing a first aromatic compound in the presence of a metal salt to yield a second aromatic compound includes combining the first aromatic compound, the metal salt, and water to yield an aqueous mixture, and heating the aqueous mixture at a temperature exceeding 200 C. to yield a reaction product that includes the second aromatic compound.
