The chemical compound "[RhCl(C8H12)(C6H4(P(C6H5)2)NHCOC6H5)]" is a rhodium-based complex with a unique structure. It consists of a rhodium atom at the center, bonded to a chloride ion (Cl) and two organic ligands. One ligand is a cyclooctadiene (C8H12), which is a conjugated diene with an eight-carbon ring. The other ligand is a modified aniline derivative, where an aniline group (NH2) is attached to a phenyl ring (C6H4), and this phenyl ring is further connected to a diphenylphosphino group (P(C6H5)2). The diphenylphosphino group is a bidentate ligand, meaning it can bind to the metal center through two points, in this case, the phosphorus atoms. Additionally, the aniline group is acylated with a phenyl group (C6H5), forming an amide linkage (NHCO). This complex is of interest in organometallic chemistry and catalysis due to its potential applications in various chemical transformations.

Check Digit Verification of cas no

The CAS Registry Mumber 99511-25-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,5,1 and 1 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 99511-25:
(7*9)+(6*9)+(5*5)+(4*1)+(3*1)+(2*2)+(1*5)=158
158 % 10 = 8
So 99511-25-8 is a valid CAS Registry Number.

Synthesis of new hybrid phosphine amide complexes of rhodium(I) and iridium(I). Intramolecular chelate-assisted oxidative addition of an N-H bond to iridium(I)

Hedden, David,Roundhill, D. Max

, p. 9 - 15 (2008/10/08)

The hybrid phosphine amide ligands o-Ph2PC6H4NHC(O)Ph (PNH(CPhO)) and o-Ph2PC6H4C(O)NHPh (P(CO)NHPh)) react with [MCl(1,5-COD)]2 to give the monomeric complexes MCl(1,5-COD)PNH(CPhO)) and MCl(1,5-COD)(P(CO)NHPh) (M = Rh, Ir). The complexes are 4-coordinate with a P-bonded monodentate phosphine amide ligand. P,N-Chelate complexes [M(1,5-COD)(PN(CPh(OH)))]ClO4 and [M(1,5-COD)(P(COH)NPh)]ClO4 (M = Rh, Ir) are formed by the addition of 1 equiv of the ligand to [M(1,5-COD)(THF)2]ClO4. The complexes are proposed to have the hybrid ligand coordinated through a nitrogen in the iminoyl form. Solutions of the complexes in acetonitrile solvent undergo intramolecular exchange. For [Rh(1,5-COD)-(PN(CPh(OH)))]+ this pathway involves replacement of the iminoyl by MeCN, but for [Rh(1,5-COD)(P(COH)NPh)]+ the process involves addition of MeCN into the fifth coordination position. In the case where iminoyl substitution occurs, the dangling ligand arm has the amide structure. The complexes RhCl(1,5-COD)(PNH(CPhO)), RhCl(1,5-COD)(P(CO)NHPh), and IrCl(1,5-COD)(P(CO)NHPh) react with base to give respectively Rh(1,5-COD)(PN(CPhO)), Rh(1,5-COD)(P(CO)NPh), and Ir(1,5-COD)(P(CO)NPh).
