Abstract

The reaction between the rhenium complexes [Re(OTf)(L)(CO)₃] (L = bipy, t-Bu₂bipy) and the alkynyl gold compounds (PPh ₄)[Au(CξCpy)₂] and (PPh₄)[Au-(CξC-C ₆H₄-CξCpy)₂] in a 2:1 molar ratio affords binuclear cationic rhenium(I) derivatives through a previously unreported alkyne transmetalation process involving the two metals. This reaction can be used for the synthesis of mononuclear rhenium alkynyls by changing the molar ratio between the reagents to 1:1. These new luminescent complexes were characterized spectroscopically. The X-ray structure of the binuclear compound [{Re(bipy)(CO)₃}₂(μ-CξCpy)](OTf) (2) was also determined.
