Abstract
Ammonolysis of 9-bromophenanthrene has been studied. Among copper metal and various copper salts tested, cupric acetate proved to be the most effective catalyst. Thus, 9-bromophenanthrene was converted into 9-aminophenanthrene in 73% yield when treated with conc, aqueous ammonia at 180200°C for 510 hrs.Phenanthrene and phenanthrazine were commonly identified as by-products. The relationships between the yields and the types or the amounts ot catalysts were also established. When cupric chloride was used, a small amount of 9-chlorophenanthrene was detected as a by-product.In the course of distillation in vacuo, a portion of 9-aminophenanthrene was found to be converted into a less volatile compound, presumably 9, 9'-diphenanthrylamine.
