An investigation of the copolymerization of cyclohexene sulfide and carbon disulfide using salphen and salen Cr complexes as catalysts and [PPN]+X- salts as cocatalysts, at different temperatures and reaction times, is reported. Both
Kinetic studies of the alternating copolymerization of cyclic acid anhydrides and epoxides, and the terpolymerization of cyclic acid anhydrides, epoxides, and CO2 catalyzed by (salen)CrIIICl

Following our interest in binary element-nitrogen compounds we report here on the synthesis and comprehensive characterization (M.p., IR/Raman, elemental analysis, 14N/133Cd/199Hg NMR) of tri-and tetraazido cadmate and mercurate anions [E(N3)(2+n)]n- (E = Cd, Hg; n = 1, 2) in a series of [Ph4P]+ and [PNP]+ ([PNP]+ = bis(triphenylphosphine)-iminium) salts. The azide/chloride exchange in CH2Cl2 as well as the formation of tetrazolate salts in CH3CN solutions of the polyazido mercurates were investigated. Single crystal X-ray structures of all new compounds, and for comparison [Ph4P][Cd2(N3)5(H2O)], were determined. Moreover, the synthesis of anhydrous cadmium(II) azide and its DMSO adduct is presented for the first time. For a better understanding of structure and bonding in E(N3)2, [E(N3)3]- and [E(N3)4]2-, theoretical calculations at the M06-2X/aug-cc-pVDZ level were carried out.
