- Abstract
Reactions of L- arginine (L- Arg) and L- histidine (L- His) with sulfamic (NH2SO3H) and methanesulfonic (CH3SO3H) acids in aq. media were investigated. The following salts (L- ArgH) (NH2SO3) (I) , (L- ArgH) (CH3SO3) (II) , (L- ArgH2) (CH3SO3) 2 (III) , (L- HisH) (NH2SO3) (IV) , (L- HisH2) (NH2SO3) 2 (V) , (L- HisH) (CH3SO3) .2H2O (VI) , (L- HisH2) (CH3SO3) 2 (VII) were obtained and characterized structurally and by vibrational spectroscopy. Large crystals of (II) , (VI) , (VII) were grown from aq. soln. by evapn. method. The crystal (IV) was known previously and characterized spectroscopically, however, the published IR spectrum significantly differs from our spectrum.
