pathways (oxidation, substitution, condensation, elimination) than the acidic conditions did. The para-quinones were major reaction products observed for all four tocopherols. Interestingly, if the quinone was substituted at C-5, it rearranged in a Michael-type addition process followed by substitution with a bromonium ion. The absence of a substituent at C-5, the presence of a bromine atom at C-7, or the

Disclosed is a process for the oxidation of at least one chroman (C1) in a solvent mixture comprising at least two solvents or in a C-bearing solvent, with a gaseous compound comprising, essentially consisting of, or consisting of oxygen in the presence of a copper catalyst, said copper catalyst exhibiting the oxidation state (+1) or (+2). A further part of the disclosure is a composition comprising at least one chroman (C1) and/or at least one quinone (C30), a solvent mixture comprising at least two solvents or a C-bearing solvent, a copper catalyst, said copper catalyst exhibiting the oxidation state (+1) or (+2) and a gaseous compound comprising, essentially consisting or consisting of oxygen. A quinone preparation and a process of making same is also part of the invention.

including the occurrence of an ortho-quinone methide, not as a radical-chain reaction, contrary to earlier reports. The ortho-quinone methide intermediate is also produced by oxidation of a-tocopherol with silver oxide and can be trapped in the presence of electron-rich dienophiles in a hetero-Diels-Alder reaction to form novel dichromanes in high yields.
