The improved hydroformylation results are obtained under mild conditions of temperature and pressure in the presence of a stabilized catalyst complex of rhodium metal, bidentate ligand and monodentate ligand represented by the formula: ##STR1## Illustrative of a preferred bidentate ligand is trans 1,...
Synthesis and crystal structure of a rhodium(III) complex bearing a hypervalent phosphorus(V) ligand as a bidentate ligand and equilibrium between bidentat... A new Rh(III) complex bearing a hypervalent phosphorus(V) ligand, Rf 2 PRh(Cp*)Cl ( 4 ) (Rf=Martin ligand; o -C 6 H 4 C(...
Although long-term colloidal stability is enhanced by using bidentate coordinating ligands over monodentate ones, other, properties such as nonspecific adsorption of target molecules and ligand exchange have not been quantified. In this study, we. modified a near-infrared dye to serve as a highly ...
As monodentate ligands, the electron-donating ligands accelerated the reaction and gave higher yields of DBCF. Concerning the effects of bidentate ligands, a π-conjugated system may be necessary for the present catalytic systems, and the systems containing 2,2'-bipyridine appeared to be more ...
