58647-73-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 58647-73-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,8,6,4 and 7 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 58647-73:
(7*5)+(6*8)+(5*6)+(4*4)+(3*7)+(2*7)+(1*3)=167
167 % 10 = 7
So 58647-73-7 is a valid CAS Registry Number.

Palladium-catalyzed cross-coupling of cyclopropanol-derived ketone homoenolates with aryl bromides

Rosa, David,Orellana, Arturo

, p. 5420 - 5422 (2013/06/27)

The cross-coupling reaction of cyclopropanol-derived ketone homoenolates bearing β-hydrogens with aryl and hetaryl bromides has been achieved for the first time. This reaction is high yielding, is broad in scope and uses a simple catalytic system. Notably, the proposed palladium homoenolates do not undergo β-hydride elimination to the corresponding α,β- unsaturated ketones.

Chemo- and diastereoselective Bi(OTf)3-catalyzed benzylation of silyl nucleophiles

Rubenbauer, Philipp,Bach, Thorsten

, p. 1305 - 1309 (2008/09/18)

The direct alkylation of silyl enol ethers with para-methoxybenzylic alcohols or their corresponding acetates was efficiently catalyzed by Bi(OTf)3 in CH3NO2 as the solvent. The reaction provided the α-benzylated carbonyl

Tandem hemiketal formation-intramolecular Friedel-Crafts alkylation: A facile route to hetero-atom-substituted benzo-fused bicyclo[3.3.1]nonanes

Wu, Yikang,Li, Yan,Wu, Yu-Lin

, p. 163 - 171 (2007/10/03)

A previously unknown intramolecular Friedel-Crafts alkylation with in situ formed hemiketals as the electrophile is reported.
