 Title    Amidinadditionsprodukte des 1,2,3-Indantrionhydrats: Synthese und Strukturzuordnung durch Kristallstrukturanalyse, spektrale Daten und Blei(IV)acetatoxidation Products o f Am idinaddition to 1,2,3-Triketohydrindenhydrat: Synthesis and Determination by Crystal Structure, Spectral Data and Oxidation with Lead(IV)acetate  
 Abstract    The addition o f amidines to 1,2,3-triketohydrindenhydrat gives cyclic dihydroxyindenoimi-dazoles. From N-substituted amidines mixtures o f regioisomeric derivatives were obtained. Analysis o f crystals revealed the major product o f 2 k to be 4 k. They belong to the monoclinic space group P 2 ,/c (a = 889.1(2); b = 1186.6(3); c = 2783.5(7) pm; ß = 91.26(2)°) with Z = 8 molecules including four molecules o f ethanole per unit cell. These results were confirmed by oxidation with lead(IV)acetate, which lead to derivatives o f isoindols.
