Tris-(2-deuterio-phenyl)-phosphane, also known as tris(2-deuteriophenyl)phosphine, is a phosphorus-containing organic compound with the chemical formula C18D18P. It is a deuterated analog of tris(2-phenyl)phosphane, where the hydrogen atoms on the phenyl rings are replaced with deuterium atoms. tris-(2-deuterio-phenyl)-phosphane is often used in chemical reactions as a ligand or a reagent, particularly in organometallic chemistry and catalysis, due to its ability to stabilize metal centers and influence reaction pathways. The deuteration can provide isotopically labeled products, which are valuable for studying reaction mechanisms and for applications in nuclear magnetic resonance (NMR) spectroscopy.

Check Digit Verification of cas no

The CAS Registry Mumber 21886-73-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,8,8 and 6 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 21886-73:
(7*2)+(6*1)+(5*8)+(4*8)+(3*6)+(2*7)+(1*3)=127
127 % 10 = 7
So 21886-73-7 is a valid CAS Registry Number.

Selective catalytic deuteration of phosphorus ligands using ruthenium nanoparticles: a new approach to gain information on ligand coordination

Bresó-Femenia, Emma,Godard, Cyril,Claver, Carmen,Chaudret, Bruno,Castillón, Sergio

supporting information, p. 16342 - 16345 (2015/11/17)

Phenyl rings in phenyl- or phenyl-alkylphosphines are selectively deuterated at the ortho position using Ru/PVP nanoparticles, while are fully reduced in the case of arylphosphine oxide derivatives and do not react in the case of arylphosphite. This different behavior provides information about the coordination mode of each ligand.
