The reactions of the trisulfur trinitride anion, S3N3-, with halogens (Cl2, Br2, I2), AsF5, SOCl2, SO2Cl2, S2Cl2, COCl2, CS2, Me3SiCl, and Ph2PCl have been investigated.In all cases these reactions gave mixtures of known sulfur-nitrogen compounds.Thus the halogens react with S3N3- to give mainly S4N4, S4N3+X- (X=Br, Cl), (SN)x, and S3N3X3 (X=Cl), while AsF5 oxidizes S3N3- to S4N4*AsF5.The major products of the reaction of S3N3- with SOCl2 or SO2Cl2 were S4N4, S4N3+Cl-, and (for SOCl2 only) S3N2O2.S3N2Cl was the main product of the reaction of S3N3- with S2Cl2, whereas COCl2 yielded (SN)x in addition to S3N2Cl and S4N4.Carbon disulfide reacts with S3N3- to give S4N2, S4N4, and CNS-.The cyclophosphathiazenes, (Ph2PN)(SN)2, 1,3- and 1,5-(Ph2PN)2(SN)2, in addition to (Ph2PN)x (x=3, 4), (Ph2PN)3*HCl and (Ph2PN)2NSCl were isolated from the reactions of Ph2PCl with S3N3- in various molar ratios.The latter reaction represents a useful alternative synthesis of the 1,5-isomer of the eight-membered ring (Ph2PN)2(SN)2.
