Crystal structures of stable arene complexes are also known, for example the benzene complex of (lR,2R)-trans-l,2-bis((diphenylphosphino)-methyl)cyclobu-tane-Rh1 [46], [Rh((R,R)-Et-DuPHOS)(benzene)]BF4 (Fig. 44.7), and [Rh((S,S)-Me-DuPHOS)(toluene)]BF4 [47]. 

S,4S)-N-tert-butoxycarbonyl-4-diphenylphosphino-2-diphenylphosphino-methyl-pyrrolidine (BPPM) (13) is an excellent bisphosphane and is also the starting material for the synthesis of PPM (14). The chiral bisphosphanes (15) have been prepared by reaction of (14) with either acid chlorides or isocyanates.
