Arenebisphosphine oxides of the general formula STR1 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 independently 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 on the ring system, or C1 -C6 -alkoxy, C3 -C8 -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 atoms may furthermore be part of an aromatic ring.
