Chloro- and bromo(alkene)iridium(I) complexes was written by Onderdelinden, A. L.;Van der Ent, A.. And the article was included in Inorganica Chimica Acta in 1972.Product Details of 39722-81-1 This article mentions the following:
Chloro- and bromo(alkene)iridium(I) complexes were prepared by the reaction of monoenes, acyclic conjugated dienes, and cyclic polyenes with the cyclooctene complexes IrX(C8H14)2 (X = Cl or Br). IrCl(C2H4)4 is an unstable 5-coordinated compound from which the planar Cl-bridged dimer [IrCl(C2H4)2]2 is formed upon ethylene dissociation From the absence of broadening of the ethylene PMR resonances in CHCl3 upon cooling to -60°,low barriers to rotation of the ethylene ligands around the metal-alkene bond were concluded. In PhMe the appearance at -60° of the frozen out-situation for the equatorial ligands suggested a considerably higher barrier for these ligands in this solution The equatorial ethylene ligands show slow exchange with free ethylene by an associative mechanism. Acyclic conjugated dienes formed 5-coordinated complexes of the type IrX(alkene)2. 1,5-Cyclooctadiene formed the dimer complexes [IrX(C8H12)]2 and the monomer complexes IrX(C8H12)2. The investigation of the bromo compounds was limited to their identification by elementary anal. and by their ir spectrum in the 4000-400 cm-1 region. Their far-ir spectra were used as an aid in the assignment of the ν(Ir-Cl) in the corresponding chloro compounds From the comparison of the far-ir spectra of corresponding chloro-(alkene)rhodium(I) and -ir(I) complexes the metal-alkene as well as the metal-Cl bonds are stronger in the Ir(I) compounds In the experiment, the researchers used many compounds, for example, Chlorobis(ethylene)iridium(I) dimer (cas: 39722-81-1Product Details of 39722-81-1).
Chlorobis(ethylene)iridium(I) dimer (cas: 39722-81-1) belongs to organic chlorides. Organic chlorides can be used in production of: PVC, pesticides, chloromethane, teflon, insulators. Aryl chlorides may be prepared by the Friedel-Crafts halogenation, using chlorine and a Lewis acid catalyst.Product Details of 39722-81-1
