Photo-induced Conversion of Aryl(trichlorovinyl)nickel(II) Complexes into Two Isomeric Mono-organonickel(II) Complexes

Abstract Photolysis (>330 nm) of trans-[Ni(CCl=CCl2)(C6H4Y)(PMe3)2] (Y= Me-4, Cl-4) resulted in the formation of two isomeric mono-organonickel(II) complexes, trans-[Ni{CCl=CCl(C6H4Y)}Cl(PMe3)2] and trans-[Ni{C(C6H4Y)=CCl2}Cl(PMe3)2], possibly by reductive elimination followed by oxidative addition.
