Studies on the Reaction of 1.8-Naphthalic anhydride with Monocarboxylic acids.

1,8-naphthalic anhydride와 일염기산의 반응

1,8-Naphthalic anhydride reacts with aromatic momocarbo-xylic acids having ${\alpha}$-hydrogen atomes such as p-nitrophenylacetic acid, p-methoxylhenylacetic acid, ${\alpha}$-naphthylacetic acid and diphenylacetic acid in the presence of freshly fused sodium acetate as a catalyst to give 1,8-(${\alpha}$-nitrophenylmalonyl)-naphthalin, 1,8-diphenylmalonyl-naphthalin, respectively. The results of these experiments show that 1,8-naphthalic anhydride yields the beta diketone type condensation products.
