The platinacyclopentane derivative (Cl) is formed by action of Cl(CH2)3PR2 on Pt(COD)2 in n-hexane via the not isolable Pt2 (R = C6H11) by oxidative addition of a C-Cl bond to platinum. (μ-ClRh(CO)2>2 reacts in benzene with Cl(CH2)3PR2 under partially CO substitution to give the stable intermediate Cl(OC)Rh2.In boiling toluene oxidative addition of a C-Cl bond to rhodium occurs under formation of the phospharhodacyclopentane Cl2(OC) (R = C6H5).The 31P<1H>-NMR spectra of the rhodium compound is characterized by an ABX system, that of the platinum by superposition of an ABX pattern with an AB spectrum.
