    Description / Table of Contents: The Chemistry of Sulfur Diimides, 81).  -  Ene Reactions with Sulfur Diimides  -  Structure of the Ene Components and Reactivity in the Reaction with Ditosyl Sulfur DiimideN,N)′-Ditosyl sulfur diimide (1) is an exceptionally reactive enophilic compound. Its reactions with many allylic derivatives give sulfinamidines 3 or  -  by sigmatropic rearrangements of 3  -  diamino sulfane derivatives 4, respectively, in good yields. Conclusions concerning relative reactivities of the ene compounds and the regio- and stereoselectivity of the reaction sequence are drawn from the results of the NMR spectrometric investigation of the reactions.
    Notes: N,N)′-Ditosylschwefeldiimid (1) ist ein außerordentlich reaktives Enophil, dessen Umsetzung mit einer großen Anzahl von Propenderivaten 2 in guter Ausbeute die Sulfinamidine 3 oder durch deren sigmatrope Umlagerung die Diaminosulfanderivate 4 liefert. Die 1H-NMR-spektrometrischen Untersuchungen dieser Umsetzungen erlauben Aussagen über die relativen Reaktivitäten der En-Komponenten und die Regio- und Stereoselektivität der Reaktionsfolge.
