Abstract

Diphenylphosphinecyrhetrene ligand (η 5 -C 5 H 4 PPh 2 )Re(CO) 3 (1) reacts with 1 equiv. of PdCl 2 (NCPh) 2 to form, after workup, the square-planar trans-[(η 5 -C 5 H 4 PPh 2 )Re(CO) 3 ]PdCl 2 (NCMe) (2). Similarly, reaction of 1 with (tetrahydrothiophene)AuCl produces, in excellent yield, the bimetallic complex [(η 5 -C 5 H 4 PPh 2 )Re(CO) 3 ]AuCl (3) with a linear P-Au-Cl moiety. From the reaction of 2 equiv. of 1 with CuBr(SMe 2 ) the planar-trigonal complex [(η 5 -C 5 H 4 PPh 2 )Re(CO) 3 ] 2 CuBr (4) was obtained. 31 P NMR and X-ray crystallography demonstrate, for the three cases, that (η 5 -C 5 H 4 PPh 2 )Re(CO) 3 acts as a monodentate ligand. The structural parameters of the bimetallic complexes are compared with related diphenylphosphinoferrocene metal complexes, described in the literature.
