Tris(2,4-dimethylphenyl)phosphine oxide, also known as TDPO, is a phosphine oxide compound with the chemical formula C21H21OP. It is a white crystalline solid that is widely used as a ligand in various homogeneous catalysts, particularly in the field of organometallic chemistry. TDPO is known for its strong electron-donating properties and its ability to stabilize metal centers, making it a valuable component in the development of catalysts for reactions such as hydrogenation, hydroformylation, and olefin polymerization. Its stability, steric bulk, and electronic properties contribute to its effectiveness in these applications, and it is often compared to other phosphine oxides like triphenylphosphine oxide (TPPO) for its performance in catalytic systems.

Check Digit Verification of cas no

The CAS Registry Mumber 52944-84-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,9,4 and 4 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 52944-84:
(7*5)+(6*2)+(5*9)+(4*4)+(3*4)+(2*8)+(1*4)=140
140 % 10 = 0
So 52944-84-0 is a valid CAS Registry Number.

Iridium(III)-Catalyzed C H Amidation of Arylphosphoryls Leading to a P-Stereogenic Center

Gwon, Donghyeon,Lee, Donggun,Kim, Jiyu,Park, Sehoon,Chang, Sukbok

, p. 12421 - 12425 (2014)

Direct C H amidation of arylphosphoryl compounds has been developed by using an IrIIIcatalyst system under mild conditions. A wide range of substrates could be employed with high functional-group tolerance. This procedure was successfully applied for the first time to the asymmetric reaction giving rise to a P-chirogenic center with a high diastereomeric ratio of up to 19:1 (90 % de).
