Abstract: Preparation of aromatic carboxylic acid ortho-esters of the formula I I where R is C1-C4-alkyl and R1 is H, halogen, alkyl, aryl, heteroaryl, alkoxy, aryloxy, acyl, acyloxy or CN, by electro-oxidizing benzene derivatives of the formula II II where R2 is CH3 or CH(OR2), in the presence of an alcohol ROH, a halogenated triarylamine compound and a base, and novel ortho-trialkyl 4-tert-butoxybenzoates, where alkyl is of 1 to 4 carbon atoms. Ortho-trialkyl 4-tert-butoxybenzoates are scents and are also used to prepared p-hydroxybenzoic acid esters.
