Abstract: A new, electrochemical method for the preparation of (I), imidazolidine-2-ones and oxazolidine-2-ones, is described, by electrolysis of formamides (II), where A = -O- or -NH- and R1, R2, R3, R4 are H, alkyl C1-C6 or aryl and X = OH or NHCHO. The electrochemical oxidation is performed in an alcohol, with an ionic halide, using graphite electrodes and a current density of 1-25 A/dm2 at temperatures up to 120 deg.C.

Abstract: Process for manufacturing benzene derivatives of the general formula in which Hal is a halogen atom, R is a hydrocarbon radical with 1 to 18 C atoms, R is a hydrogen atom or an alkyl radical with 1 to 6 C atoms and X is a hydrogen or halogen atom, in which toluene derivatives of the general formula are electrochemically oxidised in the presence of an acid of the formula R -COOH (III), and benzene derivatives of the general formula in which R is a hydrogen atom or a R -CO radical, but where R cannot be methyl when X is hydrogen, and benzene derivatives of the general formula in which R is a branched or cyclic alkyl radical with 3 to 12 C atoms, but where R cannot be isopropyl when X is hydrogen.

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.
