The ditertiary phosphines, [Formula: see text] (n = 1,2) react with [Rh(CO)2X]2 (X = Cl, Br) via unsymmetrical cleavage of the halide bridges to give ionic complexes [(P—P)2Rh]+ [cis-(CO)2RhX2]−. However the diarsine, [Formula: see text] (ffars) reacts in an anomalous manner to give the neutral dimer, [(ffars)Rh(CO)Cl]2. With an excess of the phosphines, (n = 1, 2 or 3) the ionic complexes [(P—P)2Rh]+Cl− are obtained. The physical and spectroscopic properties of the new compounds and the tendency of the ions, [(P—P)2Rh]+, not to undergo facile oxidative-addition reactions are discussed.

Abstract Some useful methods for the preparation of chlorobiphenylols have been investigated. Twenty monohydroxy and dihydroxy derivatives of chlorobiphenyls are described; 10 are new compounds and several are known metabolic products from animals or microorganisms. The relationship between structure of the chlorobiphenylols and gas chromatographic retention time as well as electron capture detector response, including those of derivatives, has been examined. The ultraviolet, fluorescence, and mass spectra of these hydroxylated derivatives have also been examined with a view towards analysis and structure elucidation of metabolites.
