“…In addition, these resonances exhibit a mutual coupling of 21 Hz, indicating that the PEt, ligands are attached to platinum in mutually cis positions. 4 The signal for PA appears as a doublet of doublets due to a three-bond coupling of 11 Hz to the heterocyclic phosphorus atom, P,. The resonance for P, is observed at 2.3 ppm, ca.…”

[Traduit par la rtdaction]The phosphadithiatriazine ring system 1 is an eight .rrelectron system, which readily undergoes cycloaddition with norbornadiene (1) o r oxidative-addition with halogens (2). The interaction of 1 with Lewis or BrGnsted acids gives adducts of the type 2 in which the electrophile (E) is attached to a nitrogen atom attached to a phosphorus atom (3). Ah irzitio Hartree-Fock-Slater SCF calculations indicate that the regiospecificity of these reactions is governed by electrostatic effects. An X-ray structural determination of the methylated derivative, 2n, reveals that coordination of 1 to an electrophile also imposes a marked perturbation on both the conformation of the ring and the S-N bond lengths (3). Specifically, the S-N bond involving the coordinated nitrogen is weakened substantially suggesting that electro-'~u t h o r to whom correspondence may be addressed.philes might be used to promote ring-opening reactions. It was of interest, therefore, to investigate the reactions of 1 with other electrophiles in order to compare the deformation of ring geometry induced by adduct formation with that observed upon N-methylation. In this study w e describe the ' 1n the SnCl, complex two molecules of 1 are coordinated to tin in a trans geometry.

. Can. J. Chem. 67, 1788 (1989). The reaction of (Me2N)3S+NSO-with sulphur has been investigated by ultraviolet-visible, infrared, Raman, and I4N, 170, and 33S nuclear magnetic resonance spectroscopies. The red species (A,,, 501 nm) formed initially is tentatively identified as SSNSO-. This anion is thermally unstable with respect to the formation of S4N-and sulphur oxyanions. Previously reported salts of the "NS02-" ion have been reinvestigated by infrared, Raman, and ' 4~ nmr spectroscopies, which indicate that the major component of these salts is the NSO-ion. The reaction of (Me2N)$S+NSO-with S4N4 is shown by 1 4~ nInr spectroscopy to produce both S3N3Op, the major product, and S3N3-.Key words: nitrogen-sulphur-oxygen (N-S-0) anions, I4N NMR spectroscopy.TR~STRAM CHIVERS, KENNETH J.
