  1 - Convenient synthesis of tetrazolo[1,5-b]pyridazine derivatives
  Maryam Manasir Mohsen Nikpour
  Reaction of 3,6-dichloropyridazine with hydrazine gave 1-(6-chloropyridazin-3-yl) hydrazine in high yield in ethanol at room temperature. Diazotization of the latter compound converted it to 6-chlorotetrazolo[1,5-b]pyridazine quantitatively in ice bath. 6-Chlorotetrazol چکیده کامل

  Reaction of 3,6-dichloropyridazine with hydrazine gave 1-(6-chloropyridazin-3-yl) hydrazine in high yield in ethanol at room temperature. Diazotization of the latter compound converted it to 6-chlorotetrazolo[1,5-b]pyridazine quantitatively in ice bath. 6-Chlorotetrazolo[1,5-b]pyridazine underwent a chlorine substitution is ethanol with amines at room temperature.The reaction mechanism and spectral data is discussed. پرونده مقاله

  2 - Condensation of thiohydrazide analogues with 4-bromo-3, 6-dichloropyridazine: an efficient rout to pyridazino[4, 3-e][1, 3, 4]thiadiazines.
  Mohsen Nikpour Mahsa Salehpoor Kiani
  Some new 3-(alkylsulfanyl)- 7-chloro-1-phenyl-1H-pyridazino [4,3-e][1,3,4]thiadiazine were synthesized by treatment of the alkyl-2-phenylhydrazinecarbodithioates with 4-bromo-3,6-dichloropyridazine in alkaline acetonitril. Orientation of the reaction has been determined چکیده کامل

  Some new 3-(alkylsulfanyl)- 7-chloro-1-phenyl-1H-pyridazino [4,3-e][1,3,4]thiadiazine were synthesized by treatment of the alkyl-2-phenylhydrazinecarbodithioates with 4-bromo-3,6-dichloropyridazine in alkaline acetonitril. Orientation of the reaction has been determined by X-Ray crystallography technique. The chlorine atom on the number 7 position of these products was replaced by secondary amines in reflux condition. پرونده مقاله

  In this work 3, 6-bis (2-[2-sulfanyl-ethylimino)-methyl]-4-(4-nitro-phenylazo)-3-metoxy-phenol) pyridazine (2) was prepared and its antibacterial properties have studied. The structures of all the newly synthesized compounds have been comfirmed by elemental analysis, IR چکیده کامل

  In this work 3, 6-bis (2-[2-sulfanyl-ethylimino)-methyl]-4-(4-nitro-phenylazo)-3-metoxy-phenol) pyridazine (2) was prepared and its antibacterial properties have studied. The structures of all the newly synthesized compounds have been comfirmed by elemental analysis, IR, 1H-NMR. Anti bacterial effects of compounds (1 and 2) have been studied. Following concentrations of materials were used: a=0.005 g/ml and b=0.01 M. Study was done on two strains of S.aureus and E.coli that experiments were done in Trypticase Soy Broth (TSB) and Nutrien Agar (TSB; Difco Laboratory). It is likely that these synthetic materials exert higher antibacterial effect on gram positive bacteria in comparison with gram negative. پرونده مقاله
