α,ω-Bis(diphenylphosphino)alkane and α,ω-bis(diphenylphosphino)(poly)ether ligands can be prepared in very high yields via reaction of the appropriate dihalide with two equivalents of LiPPh2. For the [Rh(COD)(P P)][ClO4] complexes of these ligands, the P P ligands with five or less atoms in the alkane or ether bridge form monomeric complexes via η2-coordination. In general the ligands with eight or
