Abstract: Chloro-olefins which contain a group of the formula II where Y is chlorine or hydrogen, which are prepared by a process in which a trichloromethyl compound which contains a group of the general formula I where X is hydrogen or an organic radical, is reduced with a chromium(II) salt in an aqueous medium.

Abstract: A process for the preparation of pyridine acylals of the general formula I in which R and R independently of one another can be hydrogen, C1- to C20-alkyl, C1- to C20-alkoxy, aryl, aryloxy, halogen, amido, carboxyl, cyano, C2- to C20-alkoxycarbonyl, C2- to C12-alkylcarbonyl or together can be a (CH2)p or (CH=CH)q group which is optionally substituted by C1- to C8-alkyl, C1- to C8-alkoxy, aryl, aryloxy, halogen, amido, carboxyl, cyano or C2- to C20-alkoxycarbonyl, where p represents 1 to 10 and q represents 2 to 4, R denotes hydrogen, a C1- to C20-alkyl, C3- to C20-cycloalkyl or aryl, R denotes a C1- to C12-alkyl, m represents 1 or 2, by electrochemically reacting pyridine derivatives of the general formula II in which R , R , R and m have the abovementioned meanings and n represents 0 or 1, with a carboxylic anhydride of the formula (R CO)2O, where R has the abovementioned meanings, in the presence of a transition metal salt.

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.
