Reactions of Sulfur and Sulfur Containing Species with Amines

Abstract

<p>The reactions of S4N4 with various amines, particularly benzylamines, have been investigated. Benzylamines give arylimine polysulfides, Schiff's bases and ammonia as products. The stoichiometric equation has been established. The reaction is quite sensitive to structural changes and appears limited to ring substituded benzylamines.</p> <p>Details of the reactions of primary amines with sulfur, one of the "neglected fields of research", have been investigated. Intermediates have been isolated and characterized and a reaction scheme has been proposed for the sulfur-benzylamine system. In this scheme benzylamine polysulfides and benzylidenimine polysulfides occur as cyclic intermediates. The final products are N-benzylidene benzylamine, ammonia and benzylammonia polysulfides.</p>
