Bis-phosphepines and processses for their preparation

The invention relates to bis-phosphepines of the formula (I): STR1 where: Ar--Ar is biphenyl, 1,1'-binaphthyl or 1-phenylnaphthyl, R1 independently of one another are F, (C1 -C8)-alkyl or (C1 -C8)-alkoxy, m is 0, 1, 2, 3 or 4, R2 and R3 independently of one another are H, (C1 -C20)-alkyl, (C6 -C20)-aryl, (C7 -C20)-aralkyl, (C7 -C20)-alkaryl or (C3 -C20)-cycloalkyl and R4 is (C1 -C10)-alkylene, it also being possible for the alkylene chain to contain oxygen atoms and N-alkyl groups, (C3 -C10)-cycloalkylene, (C8 -C22)-arylene-bisalkyl or (C6 -C10)-arylene, the group CR2 R3 always being adjacent to the Ar--Ar bond. The invention further relates to processes for the preparation of compounds of the formula (I).
