C-C coupling of aryl groups and allyl derivatives on Pt(II)-phenanthroline fragments: Crystal and molecular structure of the tbp [(η1, η2-2-allyl,5-methyl-phenyl)iodo(1,10-phenanthroline)platinum(II)] complex containing the N-N ligand in axial-equatorial coordination mode

The reactions between allyl compounds CH2CHCH2Fn bearing electron-withdrawing functional (Fn) groups and cationic {Pt(aryl)(1,10-phenanthroline)}+ fragments generated in situ are described. The aryl and platinum addition to the terminal and, respectively, internal unsaturated carbon is generally observed. The subsequent H-C aryl bond activation, followed by HFn elimination, affords the ortho organic fragment (Pt)-aryl-CH2CHCH2 η1, η2-chelate to the platinum. This process does not occur when the regiochemistry is of Markownikov type and the Pt-CH2CH(aryl)CH 2Fn fragment is formed. The described results are compared with those concerning the behaviour of unsubstituted α-olefins. The X-ray crystal structure of the title five-coordinate complex shows a distorted tbp arrangement of the ligands with the iodide in the equatorial plane and the unusual axial-equatorial coordination mode of the 1,10-phenanthroline.
