Thiiranes are important starting materials for the synthesis of substituted taurines. The regioselectivity of ring-opening reactions of thiiranes with ammonia in the presence of silver nitrate was investigated. The results of the ring-opening reaction and subsequent peroxy acid oxidation indicate that alkyl-substituted thiiranes give rise to 1-monoalkyl- and 1,1-dialkyltaurines, whereas aryl-substituted
