75266-51-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 75266-51-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,2,6 and 6 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 75266-51:
(7*7)+(6*5)+(5*2)+(4*6)+(3*6)+(2*5)+(1*1)=142
142 % 10 = 2
So 75266-51-2 is a valid CAS Registry Number.

Pyridine-NHC: Effective ligand in Pd-catalyzed cyclopropanation of esters with substituted allyl carbonates

Huang, Jian-Qiang,Ding, Chang-Hua,Hou, Xue-Long

, p. 12010 - 12017 (2015/01/09)

By consideration of the mechanism of Pd-catalyzed cyclopropanation and allylation, NHC-pyridine compounds were adopted as the ligand in Pd-catalyzed cyclopropanation of esters and monosubstituted allylic reagents. The corresponding cyclopropanes were affo

Cyclopropanation of Ester Enolates by ?-Allylpalladium Chloride Complexes

Hegedus, Louis S.,Darlington, W.H.,Russell, Charles E.

, p. 5193 - 5196 (2007/10/02)

Branched ester enolates react with ?-allylpalladium chloride complexes in the presence of Et3N and HMPA to produce alkylated cyclopropanes.Labeling studies indicate the carbanion attacks the central carbon of the ?-allyl complex.
