Abstract

Abstract Activation of the CÍÄC bond in acetylenic hydrocarbons, catalyzed by iodide complexes of platinum (IV), and the subsequent CÄC coupling reaction make it possible to synthesize 1, 4-diiodo-substituted dienes with high stereo-and regioselectivity. The reaction involves intermediate formation of bis-σ-vinyl platinum (IV) complexes which can be isolated in the pure state. Under similar conditions palladium (II) complexes catalyze iodine ...
