WebLigands with electron withdrawing groups at phosphorus atoms such as chiraphite, kelliphite, binaphos, and diazaphospholane reduce ligand basicity and promote catalytic activity effectively. However, more complex relationships underlie the origin of activity, and the shape of the catalyst also needs to be considered such as for the Ph-BPE ligand . Webcarbon yl complexes; R,R-chiraphite coordinates in bisequatorial f ashion in the trigonal bipyramidal rhodium complex [9] , whereas binaphos occupies an apical and an equatorial site [10] .
