Abstract
Carbon disulfide has been shown to undergo insertion reactions with [Ni(aziridine)4,6]2+ and [Ni(2-methylaziridine)4]2+. The diamagnetic products are formulated as planar dithiocarbamate complexes in which the heterocyclic ring remains intact. The complexes have properties which are atypical of all dithiocarbamate complexes heretofore reported, and infrared and optical spectral measurements suggest that the insertion products may be the first examples of N,S-bonded dithiocarbamate ligands. In methanol the products slowly rearrange to give S,S-bonded complexes in which the aziridine rings have been opened.
