Abstract

1. The reactions of benzylamine and of N-methylbenzylamine with benzalacetophenone dibromide and with α-bromobenzalacetophenone have been studied.

2. The condensations of benzylamine and of N-methylbenzylamine with benzoylacetone and with dibenzoylmethane have been investigated.

3. It has been found that benzylamine and N-methylbenzylamine react with benzalacetophenone dibromide and with α-bromobenzalacetophenone to give only α-N-benzylaminobenzalacetophenone and α-N-methylbenzylaminobenzalacetophenone, respectively.

4. Benzylamine was found to condense readily with dibenzoylmethane and benzoylacetone to give β-N-benzylaminobenzalacetophenone and l-phenyl-3-N-benzylaminobutene-2-one-1, respectively.

   It has not been possible to condense N-methylbenzylamine with benzoylacetone or dibenzoylmethane.
