18440-21-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 18440-21-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,4,4 and 0 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 18440-21:
(7*1)+(6*8)+(5*4)+(4*4)+(3*0)+(2*2)+(1*1)=96
96 % 10 = 6
So 18440-21-6 is a valid CAS Registry Number.

Suzuki-Miyaura cross-coupling reactions in water using in situ generated palladium(II)-phosphazane complexes

Amini, Mojtaba,Tarassoli, Abbas,Yousefi, Saeed,Delsouz-Hafshejani, Sepideh,Bigdeli, Mina,Salehifar, Mahnaz

, p. 166 - 168 (2014/02/14)

The phosphazane derivatives (L1-3) were readily obtained by reaction of different ratios of PCl3 and PhNH2. The L 1-3 derivatives were found to be efficient ligands in the palladium-catalyzed Suzuki CC coupling reactions in water. It was determined that with the use of L1-3/Pd(OAc)2 system as a catalyst, aryl halides undergo Suzuki cross-couplings with arylboronic acids to give the desired products in moderate to excellent yields.

1,3,2,4-Diazadiphosphetidines as ligand and base for palladium-catalyzed suzukimiyaura, sonogashirahagihara, and homocoupling reactions of aryl halides under heterogeneous conditions in water

Iranpoor, Nasser,Firouzabadi, Habib,Tarassoli, Abbas,Fereidoonnezhad, Masood

scheme or table, p. 1367 - 1373 (2011/02/22)

1,3,2,4-Diazadiphosphetidines as easily prepared, cheap, and air-stable P(III) containing ligands are successfully used for the efficient CC bond formation via SuzukiMiyaura, SonogashiraHagihara, and homocoupling reactions of aryl iodides, bromides, and chlorides. The reactions occur heterogeneously in refluxing water and the nitrogen atoms in these ligands behave as base to exclude the need to add internally base. The ligand together with its Pd(0) complex is easily separated by filtration and reused for several runs.
