 Title    Zur Reaktion von 2,4-Dioxo-4-ferrocenyl-butansäureethylester mit primären aromatischen Aminen On the Reaction of Ethyl 2,4-Dioxo-4-ferrocenyl-butanoate with Primary Aromatic Amines  
 Abstract    Starting from ethyl 2,4-dioxo-4-ferrocenyl-butanoate (1) a series of new ferrocene derivatives has been prepared. While the reaction with o-phenylene diamine leads to two ferrocene-con­ taining heterocyclic compounds, 4-ferrocenyl-3//-l,5-benzodiazepine-2-carbonic acid ethyl ester (3) and 3-(2-ferrocenyl-2-oxo-ethylidene)-3,4-dihydro-l//-quinoxalin-2-one • H20 (4), reactions with m-and /?-phenylene diamine give both the mono-and disubstituted products 5 -8, respectively. The conversion of 4 by Lawesson's reagent results in 2-ferrocenvl-thieno[2,3-b]quinoxaline (9). The new compounds have been characterized by their 'H , 1 C NMR, and mass spectra. The molecular structures of 4-ferrocenyl-4-oxo-2-phenylamino-but-2-enoic acid ethyl ester 2, and of 4 and 9 have been determined by X-ray crystal structure analysis.
