✦ Synopsis

Normal, neutral, and inverse-type Diels-Alder reactions can Extensive kinetic studies prove the highly dienophilic activity of the C=S and C=Se double bond. Studies of the be observed in [4+2] cycloadditions of thio-and selenocarbonyl compounds 1-9 with various cyclic and aryl-, solvent and temperature dependence of the reaction rate indicate a concerted mechanism. methyl-or methoxy-substituted open-chain 1,3-butadienes.
