49676-42-8 Usage
General Description
TRIS(2,4-DIMETHYLPHENYL)PHOSPHINE is a chemical compound that belongs to the class of phosphines. It is known for its strong nucleophilic properties and is commonly used as a ligand in organometallic chemistry and catalysis. The chemical structure contains three 2,4-dimethylphenyl groups attached to a central phosphorus atom, which gives it a bulky and sterically demanding nature. TRIS(2,4-DIMETHYLPHENYL)PHOSPHINE has a wide range of applications in organic synthesis, including as a reagent in cross-coupling reactions, and as a catalyst in various transformation reactions. Additionally, TRIS(2,4-DIMETHYLPHENYL)PHOSPHINE has found utility as a stabilizer in the production of polymers and as a vital component in the preparation of specialty chemicals.
Check Digit Verification of cas no
The CAS Registry Mumber 49676-42-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,9,6,7 and 6 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 49676-42:
(7*4)+(6*9)+(5*6)+(4*7)+(3*6)+(2*4)+(1*2)=168
168 % 10 = 8
So 49676-42-8 is a valid CAS Registry Number.

Reactivity-Tuning in Frustrated Lewis Pairs: Nucleophilicity and Lewis Basicity of Sterically Hindered Phosphines
Follet, Elsa,Mayer, Peter,Stephenson, David S.,Ofial, Armin R.,Berionni, Guillaume
, p. 7422 - 7427 (2017)
The nucleophilicity and Lewis basicity of sterically hindered phosphines, widely used in catalysis and in frustrated Lewis pair (FLP) chemistry, have been quantified by determining the rates and equilibrium constants of their associations with reference s
