Uses
Used in Organic Synthesis:
Dichlorobis(di-tert-butylphenylphosphine)palladium(II) is used as a catalyst for cross-coupling reactions, enabling the formation of carbon-carbon bonds between different organic molecules. This is crucial for the synthesis of complex organic compounds, including pharmaceuticals, agrochemicals, and advanced materials.
Used in Suzuki-Miyaura Coupling Reactions:
In the field of organic chemistry, dichlorobis(di-tert-butylphenylphosphine)palladium(II) is used as a catalyst for Suzuki-Miyaura coupling reactions. This reaction is a widely employed method for the formation of carbon-carbon bonds between an aryl or vinyl halide and a boron-containing compound, such as arylboronic acids or arylboronates. The catalyst plays a pivotal role in promoting the reaction, leading to the formation of biaryl and vinylarene products, which are important structural motifs in various pharmaceuticals, agrochemicals, and materials.
Check Digit Verification of cas no
The CAS Registry Mumber 34409-44-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,4,0 and 9 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 34409-44:
(7*3)+(6*4)+(5*4)+(4*0)+(3*9)+(2*4)+(1*4)=104
104 % 10 = 4
So 34409-44-4 is a valid CAS Registry Number.

As(t-Bu)3 reacts with platinum(II) chlorides to afford either trans-PtCl2[As(t-Bu)3]2 or the dinuclear complex Pt2(μ-Cl)2Cl2[As(t-Bu)3] 2. With palladium(II) chloride, however, only the dinuclear complex Pd2(μ-Cl)2Cl2[As(t-Bu)3] 2 is formed even in the presence of excess As(t-Bu)3. These complexes undergo substitution and/or bridge-cleavage reactions with CO, py, AsPh3, Cl-, or tertiary phosphines.
