dc.description.abstract | It has been reported that diazotized amines decompose in the presence of certain reducing agents to form the common replacement derivatives with other products, including biaryls. o-, m- and p- Chlorobenzoic acids were synthesized starting from o-, m- and p- aminobenzoic acids through the extended Sandmeyer reaction, respectively. The experiment was intended to know the optimum concentration of cuprous chloride solution in hydrochloric acid according to various normalities ( 12N, 10N, 8N, 6N, 4N and 2N ) when the diazotized. amine was replaced with chloride radical. The yIeld of chlorobenzoic acid considerably varied with the normality and volume of cuprous chloride solution. In the case of o- and p- chlorobenzoic acid, their maximum yields were 71.9% and 90.6% at 6N HCl, respectively. Whils the maximum yield of m-chlorobenzoic acid was 77.2% at 4N HCl. When the diazotized amine was also replaced with cyanide radical, p-cyanobenzoic acid synthesized with Sandmeyer reaction was yielded 44.3% and with tetracyanonickelate(ll)ion was yielded 41.3%. | - |
