Provided are methods and materials for the functionalization of a heteroalkane or arene using an oxidizing electrophile as a stoichiometric agent or catalyst. The reaction involves the replacement of a hydrogen atom on an sp3-hybridized carbon atom of the heteroalkane or of a hydrogen atom on an sp2-hybridized carbon atom of the arene. A main group element organometallic intermediate is formed that undergoes further conversion to a functionalized heteroalkane or arene.

Tripentyl esters of trimellitic acid, especially mixtures of triisopentyl esters of trimellitic acid comprising isomeric pentyl radicals in which more than 5 mol % of the isomeric pentyl radicals incorporated in the ester mixture are branched, have good compatibility with PVC and PVC-containing polymers and simultaneously exhibit a lesser tendency to migrate.

In an example, a process of forming a polymeric material is disclosed. The process may include chemically reacting a polyvinyl chloride (PVC) material with a diamine to form a diamine-modified PVC material. The diamine has a chemical formula (CH.sub.2).sub.x(NH.sub.2).sub.2, where x is not less than 2. The process may also include chemically reacting a halogenated phthalate plasticizer with the diamine-modified PVC material to form a polymeric material having a phthalate plasticizer covalently bonded to a polymer chain.
