Synthesis of stable phosphomide ligands and their use in Ru-catalyzed hydrogenations of bicarbonate and related substrates

New benzoyl- and naphthoyl-substituted phosphines have been synthesized, which are stable to air and moisture. Testing these so-called phosphomide ligands in the presence of different ruthenium precursors, the hydrogenation of sodium bicarbonate (NaHCO3) to sodium formate (NaHCO2) proceeded with good catalyst turnover numbers in the range of 1300-1600 at 80 C and a total pressure of hydrogen of 60 bar in the absence of amines or other additives. Similarly, catalytic hydrogenations of carbon dioxide, cinnam-, and benzaldehyde were possible with these new ruthenium complexes. As an intermediate of the catalytic cycle the defined ruthenium complex [(eta6-C6H6)-RuCl2(Cy 2P(1-naphthoyl)] (Cy=cyclohexyl) was prepared and characterized by X-ray crystallography. Ruthenium and phosphor work wonders: Air-stable ruthenium phosphomide complexes are active catalysts in the hydrogenation of sodium bicarbonate, carbon dioxide, and carbonyl compounds. Hydrogenation proceeds with high catalyst turnover numbers in the absence of amines or other additives. The application range of these new ruthenium catalysts also includes the hydrogenation of cinnamaldehyde and benzaldehyde. Copyright

Effects of changes in the ligands on the skeleton and the catalytic activity of some new rhodium complexes with pyrazolato moieties

Whereas the reaction of 2 (where pz is either a pyrazolato or 3,5-dimethylpyrazolato group) with 3-(diphenylphosphino)benzoic acid and (2-formylphenyl)diphenylphosphine gives the dinuclearic complexes 2 (1 and 2) and 2 (5 and 6) respectively, 2-(diphenylphosphino)benzoic acid gives the monorhodium compounds (3 and 4).The structures of (6) have been determined by X-ray diffraction analyses.Both, the monorhodium and the dirhodium complexes catalyse the hydroformylation of acyclic and cyclic olefins at 120 deg C and at CO and H2 pressures of 28 atm.At 70-90 deg C the dinuclear complexes with 3-(diphenylphosphino)benzoic acid moieties are substantially more active than the monorhodium compounds.Key words: Rhodium; Phosphine; Hydroformylation; X-ray diffraction

Synthesis of penta- and hexa-m-phenylenecyclophosphites and thiophosphates

New representatives of an original crown ether class-penta- and hexaresorcinolamidophosphites (7a,b and 13a,b)-were synthesized using the molecular assemblage technique. Their thio derivatives (8a,b and 14a,b) were obtained, as well as the rhodium (I) complex of hexaphosphite 13b (16). Macrocycle 15 containing both P3+ and P5+ was synthesized. 1H and 31P NMR spectroscopy data suggested the higher conformational flexibility of phosphite macrocycles.
