✦ Synopsis
z,z-Dimethylsulfurdiimide is explored as a novel and effective reagent for the direct synthesls of aromatic nitriles from aldehydes. A novel eight-membered heterocycle is isolated as a reaction intermediate and a mechanism for this reaction is discussed. Sulfurdiimides 1 belong to a relatively new class of sulfur nitrogen compounds, which have been recognized as valuable intermediates in organic synthesis.' Sulfoximides 2 and sulfilimines 3 have been subject to rather intensive studies, whereas little attention has focused so far on the chemistry of sulfurdiimides.2 However, with the
