Rhodium(I) complexes of unsymmetrical diphosphines: Efficient and stable methanol carbonylation catalysts

Rhodium complexes of unsymmetrical diphosphines of the type Ph2PCH2CH2PAr2 are catalysts for the carbonylation of methanol; several features of the catalysis are reminiscent of iridium carbonylation catalysts.

Synthesis and characterization of rhodium-aluminum heterobimetallic complexes tethered by a 1,3-bis(diphenylphosphino)-2-propanoxy group

We demonstrate the synthesis and characterization of a new class of late transition metal-aluminum heterobimetallic complexes. A bridging ligand which both chelates the transition metal and binds the aluminum via an alkoxide was employed to impart stabili

Rhodium(I) - (N-heterocyclic carbene) - Diphosphine complexes

Reactions of [RhCl(COE)(IPr)]2 (1) and [RhCl(COE)(IMes)] 2 (2) (COE = cyclooctene; IPr = N,N'-bis(2,6-diisopropylphenyl) imidazolin-2-ylidene; IMes = N,N'-bis(2,4,6-trmiethylphenyl)miidazomi-2-ylidene) with the diphosphines Ph2P(CH2)nPPh 2 and 1,2-bis(diphenylphosphino)benzene (dppbz) give the N-heterocyclic carbene (NHC)-diphosphine-rhodium(I) complexes: RhCl(NHC)[Ph 2P(CH2)nPPh2] [NHC = IPr, n =1(3); NHC = IMes, n =1 (4); NHC = IPr, n = 2 (5); NHC = IMes, n = 2 (6); NHC = IPr, n = 4 (7); NHC = IMes, n = 4(8)] and RhCl(NHC)(dppbz) [NHC = IPr (9); NHC = IMes (10)]. All the complexes are characterized by 1H, 31P{1H}, and 13C{1H} NMR spectroscopy, elemental analysis, and mass spectrometry. Complexes 3, 7, and 9 are also characterized crystallographically. In benzene solution, the complexes decompose in the presence of O2 with formation of the diphosphine dioxide, whereas reaction with CO leads to replacement of the NHC ligand to give known carbonyl-diphosphine complexes.

Preparation method of bidentate phosphine rhodium complex, bidentate phosphine rhodium complex and application thereof

The invention provides a preparation method of a bidentate phosphine rhodium complex. The method includes the steps of: in a nitrogen protection condition, adding an alcoholic solution of rhodium trichloride hydrate and a formaldehyde solution drop by drop to an alcoholic solution of a bidentate phosphine complex in order; continuously carrying out reaction for 10-60min at 50-120 DEG C; and separating the generated bidentate phosphine rhodium complex after a mixing solution is cooled. The preparation method of the bidentate phosphine rhodium complex has the advantages that raw materials are easily available, and the preparation method is simple and easy to operate, and overcomes the problem that the steps of the present preparation method are tedious and difficult to operate. The invention also provides the bidentate phosphine rhodium complex prepared by the above preparation method, and application of the bidentate phosphine rhodium complex as a catalyst to an alkene hydroformylation reaction.

Entrapment of rhodium complexes in inorganic or hybrid matrices via the sol-gel method

Rhodium complexes have been entrapped inside the porous systems of inorganic or hybrid matrices via the sol-gel method. The resulting materials were tested as catalysts in hydroformylation reactions. The microporous materials could be recycled without any rhodium leaching, being active even in the absence of a solvent. High turnover numbers were obtained in the hydroformylation of either 1-hexene or 1-decene. However, the characteristics of the matrix could not be related to the addition (or not) of a hybrid organic-inorganic co-condensation agent, but appeared to depend on the nature of the rhodium complex.
