Phosphorus- and arsenic-bridged complexes of metal carbonyls. VI. Reactions of tetrasubstituted biphosphines and a biarsine with monomeric metal carbonyls

Article abstract of DOI:10.1021/ic50015a025

The reactions of tetramethylbiphosphine and -biarsine with the carbonyls of nickel, iron, chromium, molybdenum, and tungsten and of tetraphenylbiphosphine with nickel carbonyl have been studied and two types of binuclear complexes identified. The group VI metal carbonyls also give a third type of complex, which is apparently polymeric. The infrared and proton n.m.r. spectra of the complexes are discussed, and a few simple reactions are studied.
