A concept for bisphosphane ligands was developed, in which chirality is derived from the optically active (1R,3R,4S)-menthyl substituents in PMen(2) groups and the backbone between the phosphorus units is varied (o-phenylene, 2,2'-biphenylene, 1,1'-ferrocenediyl); one of the two PMen, groups was also replaced by a PPh2 unit. The synthesis and characterisation of seven new menthylphosphanes is described. Emphasis is put on the NMR assignment of the menthyl protons by two-dimensional methods and C-13-H-1 Shift correlation. The ligands have been used in Rh and Ni complexes in several model reactions of enantioselective catalysis giving optical inductions in the low to middle range.
