coordination of the M(CO)(3)}(+) core (M = Tc, Re), and a thiol reactive maleimide group has been prepared conveniently and in high yield under Mitsunobu reaction conditions by the coupling of an appropriate alcohol derivative with maleimide. The rhenium complexes [Re(CO)(3)(Lx)]Br (x= 1-9) were prepared in good yields from the reactions of the ligands and (NEt(4))(2)[Re(CO)(3)Br(3)] in refluxing methanol

A series of bifunctional chelates containing a tridentate donor set for complexation of the M(CO)3+ core and a maleimide group for site-specific coupling to peptides and proteins containing free thiol groups has been prepared and their Re(CO)3+ complexes and glutathione conjugates structurally characterized. The flexibility of design allows preparation of ligands suitable for both fluorescence imaging, radioimaging and radiotherapeutic studies of proteins and peptides as well as other biopolymers using site specific conjugation.
