Solutions of HBr in C4H8SO2 (2,3,4,5-tetrahydrothiphen 1,1-dioxide; sulpholane) are brown in colour, due to the presence of Br2.Infrared and u.v. investigations have established that equilibrium is set up in the system with C4H8SO2 + 2HBr <*> C4H8SO + Br + H2O K = 2.4E-5 at 20 deg C ( ΔH=-55 kJ/mol and ΔS=-275 JK-1 mol-1 ).Proton n.m.r. observations of HBr-C4H8SO2 solutions show that protonation of the solvent occurs.The addition of H2O to such solutions leads to unusual n.m.r. spectra that indicate only slow exchange of H between C4H8SO2H(1+) and H2O.
