| Abstract: | A one-pot synthesis (yields over 50%) of methyl and ethyl esters from aldehydes (and the corresponding alcohol), using aromatic nitrocompounds as oxidizing agents under the catalytic action of cyanide ion or of a conjugate base of a thiazolium ion, is described. A variety of by-products (α-hydroxybenzylidenaniline) (16), α-methoxybenzylidenaniline (21), α-cyanobenzylidenaniline (27), N1-hydroxy-N1,N2-diphenylbenzamidine (28), and others) have been identified. |
