Reactions
In many respects the catalytic profile of the MeOBIPHEP ligands is similar to that of other atropisomeric diphosphines such as binap and its many analogs. The nature of the PR2 group strongly influences the catalytic performance of the metal complexes. The rhodium and ruthenium MeO-BIPHEP catalysts are highly effective for the hydrogenation of various C=O, C=C and C=N bonds and several synthetically useful C-C coupling reactions. 1. Ru and Ir catalyzed dynamic kinetic resolution for the synthesis of hydroxy, amino acid derivatives. 2. Ru-catalyzed asymmetric hydrogenation of ketones and alkenes. 3. Ir catalyzed enantioselective hydrogenation of heteroaromatic compounds. 4. Conjugate addition using 2-heteroaryl titanates and zinc reagents.Check Digit Verification of cas no
The CAS Registry Mumber 256390-47-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,6,3,9 and 0 respectively; the second part has 2 digits, 4 and 7 respectively.Calculate Digit Verification of CAS Registry Number 256390-47:
(8*2)+(7*5)+(6*6)+(5*3)+(4*9)+(3*0)+(2*4)+(1*7)=153
153 % 10 = 3
So 256390-47-3 is a valid CAS Registry Number.
