ChemInform Abstract: Formation of 1:1‐Adducts Between Bis(1,2‐Diaryl‐1,2‐ethylenedithiolato)metal(0) (Metal = Ni, Pd, and Pt) and Quadricyclane and Their Photodissociation.

Abstract

ChemInform Abstract The dithiolatometal complexes (I) are synthesized by the reaction of thiophosphoric acid esters of dithiobenzoins with nickel, palladium, or platinum salts. When refluxing the complexes (I) with quadricyclane (II) in benzene, the adducts (III) are prepared. These are also obtained when the compounds (I) reacts with norbornadiene (IV), although the reaction is much slower and the dihydrodithiins (V) are formed as by-products. The analogous reaction of (Ia) with norbornene (VI) yields the compounds (VII) and (VIII).
