S Sulfur-Nitrogen Compounds

The present volume describes acyclic Sulfur-nitrogen compounds with sulfur of the oxida tion number II. The first chapter deals with sulfur imide (S=NH), N-organyl-sulfur imides (S=NR, R = or ganyl), and metal complexes of sulfur imides. N-Organyl-sulfur imides have not been isolated, but they can be trapped, for example, by cycloaddition and stabilized by coordination to transi tion metals. 11 The following chapter present a detailed survey of other 8 -N compounds with one coordinate sulfur, e.g., dithionitrous acid (S=N-SH) and derivatives, the salts of the dithionitryl ion (1 +) ([S=N=S]+), and N-thionitroso-diorganyl-amines (S=NNR , R = organyl). Only the reac 2 tions of [S=N=S]+ AsF5, among the known [S=N=S]+ salts, have been extensively studied. Cycloadditions with alkenes and triple bonded compounds produce 1 ,3,2-dithiazolium salts and their derivatives. S=NN(CH )z and S=NN(C H )z form transition metal complexes. The 3 6 5 Iigand is coordinated via the S atom in a monodentate manner.

Klappentext

This volume treats the acyclic sulfur(II)-nitrogen compounds with one-coordinate and two-coordinate sulfur. Sulfur imide (S=NH) and N-organyl-sulfur imides (S=NR) are unstable compounds which can be stabilized by coordination to transition metals or trapped, for example, by Ä2 + 4Ü cycloaddition with 1,3-butadiene. Among dithionitryl (1+) salts, only ÄS=N=SÜ+AsF6- has been studied extensively. Cycloaddition with alkenes and triple bond compounds produce 1,3,2-dithiazolium salts. Thiohydroxylamine, HSNH2, has been detected in the gas phase. Numerous examples of N,N-diorganyl-amino-halogeno-sulfanes (XSNR2, X = F, Cl, Br, I; R = organyl) and salts of the cation (XS)2N+ (X = Cl, Br) are known. N,N-Diorganyl-amino-chloro-sulfanes are important synthetic reagents.
