Based on the molecular structures of the reaction products determined by X-ray analysis, correlations between molecular structures and reaction mechanism are reported in this article. High selectivity for electrophilic addition of Br<SUB>2</SUB> or BrOH and Michael addition of dimethyl malonate to the chiral sulf inyl compounds are explained in terms of the established configurations and conformations of the products. A study on a series of the compounds produced by Bipolar additions to thiadizoles and thiadizoline reveals that a bond switch takes place at the π-hypervalent sulfur atom during these reactions. In the last section recent topics on a relationship between reaction paths and molecular structures proposed by Burgi are reviewed.
