Abstract
1) By the reaction between N-benzylidenemethylamine and formamide, a compound of new benzylidenediamine type, namely N-benzylidene-α-formamidobenzylamine, was obtained as the main product. Hydrolysis, catalytic reduction under a high pressure, and selective catalytic reduction of this product were examined and its ultraviolet spectrum was shown, by which its structure was confirmed. 2) N-Arylmethylene-alkylamines such as N-benzylideneethylamine, N-(p-chlorobenzylidene) methylamine, and N-anisylidenemethylamine reacted in the same way with formamide to afford N-arylmethylene-1-formamido-1-arylmethylamines as in the reaction between N-benzylidenemethylamine and formamide. Moreover, N-benzylidenemethylamine and acetamide reacted similarly, affording N-benzylidene-α-acetamidobenzylamine.
