1,3-bis[(diphenylphosphino)ethynyl]benzene is a phosphorus-containing organic compound with the molecular formula C30H20P2. It is a planar, rigid, and electron-rich ligand that is widely used in homogeneous catalysis, particularly in transition metal complexes. The compound features a benzene ring with two ethynyl groups attached at the 1 and 3 positions, each bearing a diphenylphosphino group. This structure endows the ligand with unique electronic and steric properties, making it suitable for various applications in catalysis, such as olefin polymerization, hydrogenation, and cross-coupling reactions. The presence of phosphorus atoms in the ligand also allows for the formation of stable metal-phosphorus bonds, which can enhance the catalytic activity and selectivity of the resulting complexes.

7608-35-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 7608-35-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,0 and 8 respectively; the second part has 2 digits, 3 and 5 respectively.Calculate Digit Verification of CAS Registry Number 7608-35:
(6*7)+(5*6)+(4*0)+(3*8)+(2*3)+(1*5)=107
107 % 10 = 7
So 7608-35-7 is a valid CAS Registry Number.
