Synthesis, And Studying Effect Of a Solvent On The 1H-NMR Chemical Shifts of 4-Azido-N-(6-chloro-3-pyridazinyl) Benzenesulfonamide

  The compound 4-Azido-N-(6-chloro-3-pyridazinyl)benzenesulfonamide was synthesized and studied using FTIR, 1H-NMR . influence of a solvent on the experimental chemical shifts title is discussed. Small shift Δδ < 0.1 ppm were observed when switching from DMSO-d6 to CD3OD. Record marked change in valeues > 0.3 transform high-polar solvents (DMSO-d6,and CD3OD)  low-polar (CDCl3). C2-H C6-H shown have excellent linear correlation with dielectric constants DMSO-d6, CD3OD,and CDCl3 (r = 0.995). C18-H shows perfect relationship solvatochromic parameter β 0.999).
