The arene ruthenium(II) azido compounds [(p-cymene)Ru((NO)-O-boolean AND)N-3}] have been prepared by the reaction of [(p-cymene)Ru(mu N-3)Cl}(2)] with the corresponding ligands. The ruthenium azido compounds [(p-cymene)Ru((NO)-O-boolean AND)N-3}] undergo 1,3-dipolar additions with substituted alkynes at room temperature to give the (eta(6)-arene) ruthenium triazolato compounds [(p-cymene)Ru((NO)-O-boolean AND)N3C2(CO2R)(2)}]. The compounds were characterized on the basis of FTIR, NMR (H-1 and C-13) and the molecular structure of a representative compound has been established with the help of single crystal X-ray diffraction.
