General Description
Tris[(4-methylphenyl)ethynyl]phosphane is a chemical compound consisting of three molecules of (4-methylphenyl)ethynylphosphane, a phosphorus compound containing three phenyl groups linked to the phosphorus atom. tris[(4-methylphenyl)ethynyl]phosphane is commonly used as a ligand in organometallic chemistry due to its ability to coordinate with metal ions and facilitate various catalytic reactions. It is also used in the synthesis of various organic compounds and materials. Tris[(4-methylphenyl)ethynyl]phosphane is a white crystalline solid that is stable under normal conditions, but should be handled with care due to its potential toxic and irritating properties.
Check Digit Verification of cas no
The CAS Registry Mumber 4319-05-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,1 and 9 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 4319-05:
(6*4)+(5*3)+(4*1)+(3*9)+(2*0)+(1*5)=75
75 % 10 = 5
So 4319-05-5 is a valid CAS Registry Number.

New Approach to Phosphinoalkynes Based on Pd- and Ni-Catalyzed Cross-Coupling of Terminal Alkynes with Chlorophosphanes
Beletskaya, Irina P.,Afanasiev, Vladimir V.,Kazankova, Marina A.,Efimova, Irina V.
, p. 4309 - 4311 (2007/10/03)
(Equation presented) The first example of direct phosphination of terminal alkynes with chlorophosphanes catalyzed by Ni or Pd complexes is described. Both aromatic and aliphatic terminal acetylenes undergo the coupling reaction to give corresponding coup
