J. Clews et al., A MILD AND SELECTIVE ROUTE TO P-QUINOMETHANES USING DIANISYLTELLURIUMOXIDE, Journal of the Chemical Society. Perkin transactions. I, (6), 1998, pp. 1009-1011
The o-quinones formed by chemical or enzymatic oxidation of 4-cyanomet
hylcatechols rapidly rearrange to isomeric p-quinomethanes which can b
e trapped: the structures of previously described 4-cyanomethyl-1,2-na
phthoquinones are revised.
