Reactions of benzynenickel(0) complexes with thioalkynes: Preparation and coordination of polydentate thioethers containing a 2,3-naphthylene backbone.

Double insertion reactions of the thioalkynes MeC≡CS-p-Tol and (MeC≡CSCH2CH2)2S with benzyne-nickel(O) complexes have been used to prepare the 2,3-di(thioether) naphthalene species 2,3-(p-TolS)2-l,4-Me2C10H4 (4) and the 2,3-naphthotrithiacyclononane
