     a new palladium-bidentate complex [m-c6h4(ch2imme)2(pdcl2)] (iii) was prepared in two steps. in the first step, [m-c6h4(ch2immeagcl)2] (ii) (im = imidazole moiety) was obtained by reacting imidazolium salt [m-c6h4(ch2imme)2]cl2 (i) (prepared by quaternisation of nmethylimidazole with 1,3-bis(chloromethyl)benzene) and ag2o in ch2cl2. in the next step, treatment of (ii) with pd(ch3cn)2cl2 afforded complex iii which was evaluated for its catalytic activity for c-c bond-formation reactions by examining the coupling reaction of 3-iodoanisole with phenylacetylene in the sonogashira reaction. in addition, 3-methoxybiphenyls were obtained with good to excellent yields by suzuki coupling reactions of 3-iodoanisole with phenylboronic acids or phenylborates salts in the presence of this complex.
