Chemistry of carbonyl sulfide. Final report, 1 July 1983-30 June 1984. [Lanthanide complexes of monothiocarbamates]

This report details research into the chemical properties ad structure of carbonyl sulfide, COS. Lanthanide complexes of monothiocarbamates have been prepared and investigations of displacement reactions begun. Diels-adler reactions of COS have been investigated as have COS ene reactions. Theoretical calculations of the structures of COS-metal complexes have been performed. These calculations indicate a preference for bonding by Ti and Fe to the oxygen end of COs forming a linear complex. In the case of nickel, bonding is to the C-S bond. In all cases the C-S bond is substantially lengthened, suggesting resultant elimination of sulfur. Additional calculations have been carried out on H/sub 4/Ti(COS), Ti(OCO), Ti(SCS), and Ti(H/sub 2/S), but only preliminary results are available on these systems. 10 references, 2 figures, 4 tables.
