Abstract

Reactions of the tricarbonylrhenium halide cations [Cp*Re(CO)₃X]⁺ (Cp* = η)⁵-C₅Me₅, X = Cl, Br and I) with azide ion are described, leading to dicarbonylisocyanate complexes trans-Cp*Re(CO)₂(NCO)X. The trans orientation of the carbonyl groups in these complexes was assigned by IR spectroscopy and by comparison with the known complexes Cp*Re(CO)₂X₂ and Cp*Re(CO)₂(COOR)(X). Some details concerning the mechanism of the formation of only one isomer is also included.
