Carbonaceous fragments of osmium ligand deficient clusters that take part in alkane C-H and C-C bonds cleavage in the presence of molecular hydrogen

The direct participation of carbonaceous ligands of osmium ligand deficient clusters (LDC) in alkane and cycloalkane reactions in the presence of H₂ is proved by¹⁴C-labeling. In contrast to the other metallic catalysts, wherein carbonaceous ligands block active centres, the C-containing ligands of the Os-LDC are active and exhibit at least two functions in alkane and cycloalkane reactions: stabilization of clusters against agglomeration and preservation of active centres.Deceased on the 7th of January 1991.
