  �ber Reaktionen von Alkylbiguaniden mit Benzoin beimpH der Biguanidbasen

  摘要：

  Alkylbiguanides 2 a-e react with benzoin (1) at the pH of the base in different ways. 1 undergoes in presence of 2 a, c oxidation to benzoic acid which reacts with the bases 2 a, c to yield 4-phenyl-1,3,5-triazinamines 3 c, 4 c; in presence of 2 b 1 is transformed to benzil, which reacts with 2 b under rearrangement to yield 1-(4-oxo-5,5-diphenyl-2-imidazolin-2-yl)-3,3-dimethylguanidine (5 b). However, the cycloalkylbiguanides 2 d, e react in presence of nitrogen as well as oxygen with 1 to yield piperidine-1-[N-(4,5-diphenylimidazol-2-yl)-carboxamidine] (7 d), resp. morpholine-4-[N-(4,5-diphenylimidazol-2-yl)-carboxamidine] (7 e). The structure of 7 e was established by means of an X-ray structure analysis. All proton- and carbon resonances were assigned on the basis of 2-dimensional NMR data.
