NOVELTY - A graphene covalently supported bipyridine metal complex (I), is new. USE - Compound (I) used as catalyst to catalyze Suzuki-Miyaura coupling reaction of phenylboronic acid and bromobenzene (claimed). ADVANTAGE - The compound (I) exhibits excellent catalytic activity, high selectivity, stable structure and recyclable cycle performance. DETAILED DESCRIPTION - A graphene covalently supported bipyridine metal complex of formula (I), is new. M = Cu, Ni or Pd; and n = 0-8. INDEPENDENT CLAIMS are included for the following: (1) preparation of the compound (I); (2) use of the compound (I) as catalyst to catalyze Suzuki-Miyaura coupling reaction; and (3) Suzuki-Miyaura coupling reaction of phenylboronic acid and bromobenzene, which involves adding acetonitrile, phenylboronic acid, bromobenzene and the compound (I) to round bottom flask in sequence, stirring, monitoring the reaction condition by thin layer chromatography, filtering the reaction mixture while it is hot, separating and recovering the compound (I), separating the filtrate, purifying to obtain biphenyl product, choosing an appropriate solvent to wash the catalyst according to the different raw materials of the reactants, and recycling after drying.
