General Description

TRICHLORO[1,1,1-tris(diphenylphosphinomethyl)ethane]rhodium(III) is a complex compound consisting of a rhodium(III) metal center surrounded by three chloro ligands and a tris(diphenylphosphinomethyl)ethane ligand. TRICHLORO[1,1,1-TRIS(DIPHENYLPHOSPHINOMETHYL)ETHANE]RHODIUM(III) is commonly used as a catalyst in various organic reactions, including hydrogenation, hydroformylation, and carbon-carbon bond formation. The tris(diphenylphosphinomethyl)ethane ligand provides stability to the metal center and enhances its reactivity towards the substrate molecules. The presence of chlorine atoms helps in coordinating with the substrate molecules and facilitating the catalytic process. Overall, this compound serves as an efficient and versatile catalyst in organic synthesis and industrial processes.

Check Digit Verification of cas no

The CAS Registry Mumber 62792-06-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,2,7,9 and 2 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 62792-06:
(7*6)+(6*2)+(5*7)+(4*9)+(3*2)+(2*0)+(1*6)=137
137 % 10 = 7
So 62792-06-7 is a valid CAS Registry Number.

η3-MeC(CH2PPh2)3/rhodium complexes utilize phosphine arm dissociation mechanisms at 25°C

Thaler, Eric G.,Folting, Kirsten,Caulton, Kenneth G.

, p. 2664 - 2672 (2007/10/02)

Reaction of RhMe3(triphos) (triphos = MeC(CH2PPh2)3) with CO generates acetone and RhMe(CO)(triphos), which reacts with further CO to give Rh[C(O)Me](CO)(triphos). The structure of RhMe(CO)(triphos) shows one strained P-Rh-P bond angle between equatorial ligands (90.80 (5)°) in a trigonal bipyramid, together with intramolecular steric effects that cause a small equatorial CO-Rh-axial(CH3) C/C angle of 79.09 (25)°. The acetyl and methyl complexes react with H2 at 25°C to produce acetaldehyde and methane, respectively, together with RhH(CO)(triphos). Reaction of CO with RhH3(triphos) is even faster than with RhMe3(triphos) to give H2 and RhH(CO)(triphos), together with a CO hydrogenation product. These results show that these clean stoichiometric conversions, as well as a variety of isotopic exchange reactions of the Rh(I) and Rh(III) compounds with D2 and 13CO, occur by preequilibrium dissociation of one arm of the triphos ligand at 25°C. One such species, Rh[C(O)Me](CO)2(η2-triphos), is directly detectable and reveals the mechanism of exchange of Rh[C(O)Me](13CO)(triphos) with 12CO. The coordination of CO to Rh(H)3(η2-triphos) is proposed to generate a dihydrogen complex, thus accounting for the CO-induced elimination of H2. As suggested by these individual reactions, RhH(CO)(triphos) is a catalyst for olefin hydroformylation. The high n:iso selectivity mimics that of RhH(CO)(PPh3)3 in the presence of a large amount of added PPh3, a beneficial consequence of the chelate effect.

Ott, J.,Venanzi, L. M.,Ghilardi, C. A.,Midollini, S.,Orlandini, A.

, p. 89 - 100 (2007/10/02)

The syntheses of (8, triphos=CH3C(CH2PPh2)3) and the related compound (triphos-I=EtC(CH2PPh2)3) are described, and the X-ray crystal structure of the latter is reported.The crystals are monoclinic space group P21/a, a 15.985(6), b 19.683(7), c 11.900(4) Angstroem, β 103,73(6) degree, Z=4.The structure was solved by the heavy atom method and refined by full-matrix leastsquares to the conventional R factor value of 0.057 for 2649 observed reflections.The metal atom is octahedrally coordinated by three phophorus atoms and by three hydrogen atoms, each trans to one phosphorus.Complex 8 has been shown to react with CO to give (2).Compound 2 reacts with CH2=CHCO2Me to give only the branched insertion product .The complex has been re-investigated and was obtained in a single isomeric form which has been assigned a five-coordinate structure.The five-coordinate compounds (X=Br and I) are also described.
