726205-37-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 726205-37-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,2,6,2,0 and 5 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 726205-37:
(8*7)+(7*2)+(6*6)+(5*2)+(4*0)+(3*5)+(2*3)+(1*7)=144
144 % 10 = 4
So 726205-37-4 is a valid CAS Registry Number.

Palladium complexes with metallocene-bridged bidentate diphosphine ligands: Synthesis, structure, and catalytic activity in amination and cross-coupling reactions

Gusev, Oleg V.,Peganova, Tat'yana A.,Kalsin, Alexander M.,Vologdin, Nikolai V.,Petrovskii, Pavel V.,Lyssenko, Konstantin A.,Tsvetkov, Aleksey V.,Beletskaya, Irina P.

, p. 2750 - 2760 (2006)

The syntheses and characterization of series of new metallocene-bridged diphosphines and the structures of complexes of some of them with Pd(II) are reported. These complexes were examined as the catalysts in amination reactions of halogenoarenes and in the Suzuki reaction. The complexes based on ruthenocene (2) and osmocene (3) showed lower activities then the palladium complex with dppf in amination reactions and the same activities in the Suzuki reaction. New palladium complexes with the bidentate bulky and electron-rich ligands Fe(η5-C5H4P(o-PriC 6H4)2)2 (6) and Feη5- C5H4P(o-MeOC6H4)2) 2 (5) showed a very high catalytic activity in amination and Suzuki coupling of aryl bromides. A complex with ligand 6 was used in the amination of 4-bromotoluene by primary and secondary amines and showed excellent activity.
