79757-20-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 79757-20-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,7,5 and 7 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 79757-20:
(7*7)+(6*9)+(5*7)+(4*5)+(3*7)+(2*2)+(1*0)=183
183 % 10 = 3
So 79757-20-3 is a valid CAS Registry Number.

Palladium-catalyzed α-arylation of zinc enolates of esters: Reaction conditions and substrate scope

Hama, Takuo,Ge, Shaozhong,Hartwig, John F.

, p. 8250 - 8266 (2013/09/24)

The intermolecular α-arylation of esters by palladium-catalyzed coupling of aryl bromides with zinc enolates of esters is reported. Reactions of three different types of zinc enolates have been developed. α-Arylation of esters occurs in high yields with i

Palladium-catalyzed α-arylation of esters and amides under more neutral conditions

Hama, Takuo,Liu, Xiaoxiang,Culkin, Darcy A.,Hartwig, John F.

, p. 11176 - 11177 (2007/10/03)

Two procedures for the ∞-arylation of carbonyl compounds under conditions that are more neutral than those of reactions of aryl halides with alkali metal enolates are reported. The first procedure rests upon the development of catalysts bearing the hindered pentaphenylferrocenyl di-tert-butylphosphine (Q-phos) and the highly reactive dimeric Pd(I) complex {P(t-Bu)3]PdBr}2. By this procedure, zinc enolates prepared from ∞-bromo esters and amides react with aryl halides to form ∞-aryl esters and amides in high yields under mild conditions with 1-2 mol % catalyst and with remarkable functional group tolerance. By the second procedure, silyl ketene and silyl ketimine acetals react with aryl bromides in the presence of substoichiometric zinc fluoride, 1 mol % Pd(dba)2, and 2 mol % P(t-Bu)3 in DMF solvent at 80 °C. Reactions of zinc tert-butyl acetate and propionate enolates and trimethylsilyl ketene acetals of tert-butyl propionate and methyl isobutyrate with aryl bromides bearing electron-donating and potentially reactive, base-sensitive electron-withdrawing groups and with pyridyl bromides are reported. In addition, the diastereoselective coupling of phenyl bromide with an imide enolate bearing the Evans auxiliary is reported, and this study shows that racemization of base-sensitive stereocenters does not occur during the coupling process under these more neutral conditions.
