The chemical compound "[RhCl(PPh3)(1,2-bis(diphenylphosphino)ethane)]" is a rhodium-based complex with a chloride ligand, a triphenylphosphine (PPh3) ligand, and a 1,2-bis(diphenylphosphino)ethane ligand. This complex is often used as a catalyst in various chemical reactions, particularly in homogeneous catalysis. The 1,2-bis(diphenylphosphino)ethane ligand is a bidentate ligand, meaning it can bind to the central metal atom (rhodium in this case) at two points, which helps to stabilize the complex and influence its catalytic activity. The combination of these ligands with rhodium results in a highly active and selective catalyst that can facilitate a range of chemical transformations, such as hydrogenation, hydroformylation, and other processes.

Check Digit Verification of cas no

The CAS Registry Mumber 55622-69-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,6,2 and 2 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 55622-69:
(7*5)+(6*5)+(5*6)+(4*2)+(3*2)+(2*6)+(1*9)=130
130 % 10 = 0
So 55622-69-0 is a valid CAS Registry Number.

Thermodynamics of homogeneous hydrogenation. Part VI. Thermodynamics of the homogeneous hydrogenation of cyclohexene catalyzed by Rh(I) and Ir(I) complexes of polydentate phosphine ligands

Taqui Khan, M. M.,Taqui Khan, Badar,Begum, Safia,Ali, S. Mustafa

, p. 43 - 58 (2008/10/08)

The oxidative addition of H2 to the mixed ligand Rh(I) complex [RhCl(PPh3)(diphos)] 1 and the Rh(I) and Ir(I) complexes of the terdentate ligands NP3, [N(CH2CH2PPh2)3] and triphos, [PhP(CH2CH2PPh2)2], MLCl 2-5 (where M = Rh(I), Ir(I); L = NP3, triphos) proceeds at 30°C and 1 atm of H2 in ethanol-benzene. The homogeneous hydrogenation of cyclohexene catalyzed by complexes 1-5 was investigated in the temperature range 10-40°C at 0.6-1 atm of H2 partial pressure. Thermodynamic parameters for the formation of the dihydrido complexes of 1-5 and the monoolefin complexes of Rh(I) and Ir(I) were computed. The activation parameters corresponding to the rate constant k for the homogeneous hydrogenation of cyclohexene were also calculated.
