Ni O -Complexes as Redox Catalysts

As ligands, phosphanes have proven to be useful (Table 7, No. 2-4). Poly(l,4-paraphenylene) is obtained on a preparative scale starting from aromatic dihalides (Table 7, No. 3, 4). The electrochemical generation and 

Ethene and mono-substituted alkenes can be arylated by aryl halides in presence
