Die Alkoholyse von 3.5-Difluor-1.1.3.5-tetraoxo-2-alkyl-1λ6.3λ6.5λ6.2.4.6- trithiatriazin / The Alcoholysis Reaction of 3,5-Difluoro-l,l,3,5-tetraoxo-2-alkyl-1λ6,3λ6,5λ6,2,4,6-trithiatriazin

(NSOF) (CH NSO ) 2a reacts with methanol to give sulfuric acid, aminosulfuric acid and SO (NHCH as final products. The primary reaction was studied by H and F NMR spectroscopy. A 1:1 adduct 2a · CH OH (=3) and a monosubstituted product which has the formula (NSOF)(NSOOCH )(CH NSO were detected to be intermediates. As 2 a is chiral, the reaction with racemic butanol-2 proceeds via diastereomeric inter-mediates which were identified by their F NMR spectrum. The reaction pattern of 2a is explained.
