the corresponding complexes cAAC·SnBr2, 3b, cAAC·SnCpCl, 3c, and cAAC·SnCpBr, 3d, which were studied in solution and in the solid state. Although isolatable as crystalline solids, 3c,d exist in a heteroleptic/homoleptic equilibrium with other tin(II) species, in solution. In addition, the coordination chemistry of 3b was investigated and the corresponding iron tetracarbonyl complex, 5, could be isolated

Three ruthenium complexes bearing backbone-monosubstituted CAACs were prepared and displayed dramatic improvement in catalytic efficiency not only in RCM reaction but also in the ethenolysis of methyl oleate, compared to those bearing backbone-disubstituted CAACs.
Late transition metal complexes of certain neutral iminophosphine ligands are useful as components of polymerization catalysts for olefins. Useful metals in the complexes include Ni, Pd, Fe and Co. Oligomers and/or polymers of olefins such as ethylene can be made.
