Three isomers of C6H4(OPF2)2, two of (C6H4OPF2)2, and seven of C10H6(OPF2)2 have been prepared by reactions of S(PF2)2 and the appropriate dihydroxy derivatives of benzene, biphenyl, and naphthalene, respectively.From these bidentate ligands, complexes have been prepared containing two Mo(CO)5 units or one Mo(CO)5 and one W(CO)5 unit linked by the ligands.With tetracarbonyl(norbornadiene)molybdenum, cyclic products with ligands bridging between cis-Mo(CO)4 units are formed.The relative stabilities of the various cyclic oligomers depend on the distance between the phosphorous donor sites, which varies widely in this set of ligands.
