Abstract: The invention relates to a method for the electrolytic oxidative alkoxylating cleavage of 1,2-diarylethane derivatives by electrolytically oxidizing the respective 1,2-diarylethane derivative in a solvent containing the alcohol required for alkoxylation, electrolytic oxidation being performed on a diamond electrode. The inventive method makes it possible to especially produce diaryl derivatives when a 1,2-diarylethane derivative in which the two aryl radicals are directly bonded to each other is used as a substrate.

Abstract: In a process for producing an arylboronic acid ester (arylboronic acid ester I), an arylchloride, arylbromide or aryliodide (halogenated aryl compound II) is coupled with electrochemical reduction to a boric acid or boronic acid ester (boric or boronic acid ester IM) or to an 1,1,2,2-tetraalkoxydiborane (tetraalkoxydiborane IV).

Abstract: A process for the preparation of 2,5-dihydrofuran derivatives substituted in the 3- or 4-position, which in the 2- or in the 5-position or at both positions each carry a C 1 - to C 6 -alkoxy radical (DHF-alkoxy derivatives 1), or 1,1,4,4-tetraalkoxy-but-2-ene derivatives substituted in the 3- or 4-position, from 2-butene-1 ,4-diol derivatives of the general formula (I) in which the radicals R 1 and R 2 independently of one another are hydrogen, C 1 - to C 6 -alkyl, C 6 - to C 12 -aryl or C 5 - to C 12 -cycloalkylene or R 1 and R 2 , together with the double bond to which they are bonded, form a C 6 - to C 12 -aryl radical or a mono- or polyunsaturated C 5 - to C 12 -cycloalkyl radical, or from their mixture with 2,5-dihydrofuran derivatives substituted in the 3- position or 4-position, which in the 2- or in the 5-position carry a C 1 - to C 6 -alkoxy radical, by electro-chemical oxidation in the presence of a C 1 - to C 6 -monoalkyl alcohol.
