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.
