    Abstract: An efficient, selective and simple route for the synthesis of 2-Naphthyl acetate has been developed. In reflux conditions the acetylation of 2-naphthol acetylation with a catalytic amount of Nickel nitrate catalysts afforded 2-Naphthyl acetate in moderate to excellent yields. Nickel nitrate showed the best catalytic performance compared to other Ni... Show More

    Abstract: Homocoupling of terminal alkynes to 1, 3-diynes has been investigated, using AuCl3 as catalyst under mild and operationally simple conditions. Effect of different organic and inorganic bases on the product yield and the reaction time were also studied. The catalyst is efficient, furnishes good to excellent yield of the desired products with organic... Show More
