Abstract of the Disclosure: Arenebiaphosphine oxides of the general formula Image I where R1 to R4 independently of one another are each hydrogen, C1-C6-alkyl, C1-C6-alkoxy, C5-C10-aryl, C5-C12- aryloxy or C7-C14-arylalkoxy, R5 and R6 independantly of one another may each be C1-C6-alkyl, C5-C10-cycloalkyl or C5-C12-aryl, each of which may furthermore contain one or two nitrogen or sulfur atoms in the ring system or carry one or two halogen atoms or C1-C6-alkyl or C1-C6-alkoxy groups as substituent of the ring system, or C1-C6-alkoxy, C3-C3-alkoxyalkoxy, C5-C12-aryloxy or C7-C14-arylalkoxy, or R5 and R6 together form a bridge of 2 to 10 carbon atoms, in which some of the carbon atom may furthermore be part of an aromatic ring.
