Electrooxidative Functionalizations of Dehydroabietic Acid [PDF]
Bulletin of the Chemical Society of Japan, 1987 Abstract Dehydroabietic acid methyl ester (1) was converted into 7-acetoxydehydroabietic acid methyl ester by direct electrooxidation in acetic acid and 7-oxodehydroabietic acid methyl ester by ruthenium dioxide-mediated oxidation. Non-Kolbe type electrodecarboxylation of 1 resulted in the introduction of a double bond into the ring A of

Photolysis of Abietic Acid to Dehydroabietic Acid and Hydrogen
Spectroscopy Letters, 1994 Abstract Abietic acid, which is the terpene acid component of natural colophony, was irradiated at above 300 nm in the presence of benzophenone and a colloidal platinum catalyst. The expected product of dehydroabietic acid was formed to the extent of 81 %, hydrogen generation occurred to a negligibly small amount.
