Displacement of the arene in (η-arene)Cr(CO)2(CX) (arene=C6H6; PhCO2Me; X=S, Se) by teriary phosphite ligands (L=(RO)3P; R=Me, Et, n-Bu, Ph) and tridentate tertiary phosphine ligands (L-L-L=triphos-U, triphos=) affords a convenient synthetic route to new series of isomeric complexes of stoichiometry Cr(CO)2(CX)L3 and (L-L-L)Cr(CO)2(CX).The stereochemistries of these isomers have been established on the basis of their FT-IR (ν(CO) region) and 31P NMR spectra.The influence of the different chalcocarbonyl ligands (CO, CS, CSe) on the positions of the 31P resonances is discussed.
