(2012) Çelik, İsmail; Akkurt, Mehmet; Yılmaz, Makbule; Tutar, Ahmet; Erenler, Ramazan; Granda, Santiago García
In the title compound, C9H8Br2O, the cyclo-pentene ring adopts an envelope conformation with the brominated C atom as the flap. In the crystal, molecules are linked by strong O - H?O hydrogen bonds into zigzag C(4) chains along [010]. In addition, a C - H?? inter-action involving the benzene ring and the H atom attached to the hydroxy-lated C atom is observed.
Synthesis of bromoaminoindane and bromoaminoindanone derivatives
(Science Reviews 2000 Ltd, 2013) Yılmaz, Makbule; Tutar, Ahmet; Erenler, Ramazan
The bromination reactions of 5-aminoindane, 5-acetamidoindane, and 5-acetamidoindan-1-one were investigated using NBS, molecular bromine and photobromination, and the optimum reaction conditions were presented. The reaction of 5-aminoindane with glacial acetic acid at reflux temperature resulted in the formation of 5-acetamidoindane in high yield. 5-Acetamidoindan-1-one was generated by the reaction of 5-acetamidoindane with CrO3 in acetic acid. Selective bromination at C-6 position of 5-acetamidoindane was achieved by treatment of title compound with bromine in acetic acid and thus afforded 5-acetamido-6-bromoindane. Further bromination reactions of bromoindanones were achieved in various reaction conditions.
