Abstract(nC3H7)As(CN)2 (1) reacts with CO2(CO)8 (2) to yield the cluster 3 in which two (nC3H7)As fragments are coordinated to Co(CO)n (n = 1, 2, 3) groups. The cluster 3 has been characterizedby analytical and spectroscopic data and by an X -ray analysis.

The reaction of (o-MeSPh)-N-functionalized tetrahydropyrimidinium salts with KN(SiMe3)2 and [Rh(COD)Cl]2 in THF leads to the formation of a novel dimeric RhIII bis-carbene complex. The reaction involves the unexpected cleavage/oxidative addition of the aryl-sulfur bond to give dimeric metallated RhIII with bridging MeS< moieties. This unusual reaction is probably a consequence of the sterically imposing structure and strong donor capacity of ring-expanded N-heterocyclic carbenes (RE-NHCs). An X-ray structure of the [(Ph,DIPP-NHC)Rh(Cl)(SMe)2] product complex has been obtained, and DFT studies were undertaken to gain an insight into the reaction pathway.

S4N4 reacts at 25 °C with trifluoro and trichloro acetic acid anhydride, respectively, to yield yellow crystalline CX3–CO–NS3N2 (X = F, Cl), the mass, infrared, and Raman spectra of which are reported. An X-ray structure analysis of monoclinic CF3CONS3N2 revealed a non-planar five-membered S3N2 ring containing an unusually long (2.206 A) sulfur-sulfur bond with one sulfur atom additionally connected to an exocyclic nitrogen atom by a multiple bond. Comparisons with the infrared spectra of S3N2O and ten compounds of type RNS3N2 allowed to identify four wavenumbers characteristic for the S3N2 ring. The relationship μ = 23.09d-27.27 has been derived for stretching vibrational wavelengths, μ (in μm), and bond distances, d (in Å), of sulfur-nitrogen bonds.
