2567-29-5 Usage

Uses

4-(Bromomethyl)biphenyl is a biphenyl derivative used in the preparation of various pharmaceutical compounds such as protein tyrosine phosphatase 1B inhibitors. 4-(Bromomethyl)biphenyl is useful as as atom transfer radical polymerization initiator.

Check Digit Verification of cas no

The CAS Registry Mumber 2567-29-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,5,6 and 7 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 2567-29:
(6*2)+(5*5)+(4*6)+(3*7)+(2*2)+(1*9)=95
95 % 10 = 5
So 2567-29-5 is a valid CAS Registry Number.

Palladium(II) complexes of Y,C,Y-chelated phosphines: Synthesis, structure, and catalytic activity in Suzuki-Miyaura reaction

Reznicek, Tomas,Dostal, Libor,Ruzicka, Ales,Kulhanek, Jiri,Bures, Filip,Jambor, Roman

experimental part, p. 173 - 179 (2012/04/23)

The phosphines L1PPh2 (1) and L2PPh 2 (2) containing different Y,C,Y-chelating ligands, L1 = 2,6-(tBuOCH2)2C6H3 - and L2 = 2,6-(Me2NCH2) 2C6H3-, were treated with PdCl 2 and di-Aμ-chloro-bis[2-[(N,N-dimethylamino)methyl]phenyl- C,N]-dipalladium(II) and yielded complexes trans-{[2,6-(tBuOCH 2)2C6H3]PPh2} 2PdCl2 (3), {[2,6-(Me2NCH2) 2C6H3]PPh2} PdCl2 (4), {[2,6-(tBuOCH2)2C6H 3]PPh2}Pd(Cl)[2-(Me2NCH2)C 6H4] (5) and {[2,6-(Me2NCH2) 2C6H3]PPh2}Pd(Cl)[2-(Me 2NCH2)C6H4] (6) as the result of different ability of starting phosphines 1 and 2 to complex PdCl2. Compounds 3-6 were characterized by 1H, 13C, 31P NMR spectroscopy and ESI-MS. The molecular structures of 3,4 and 6 were also determined by X-ray diffraction analysis. The catalytic activity of complexes 3-6 was evaluated in the Suzuki-Miyaura cross-coupling reaction.
