Synthesis
In 100ml round-bottomed flask, by 2-cyclopenta ethyl benzoylacetate (10.6g, 43.05mmol, 1.0eq), NaOH (2.6g, 64.5mmol) and Na2CO3(4.5g, 43mmol), is suspended in 50.0mLH2In O, it is warmed up to 80 DEG C and reacts 3 hours, obtain product phenylcyclopentyl ketone.Purify: reactant liquor is cooled to room temperature, extract 3 times with ethyl acetate 20mL；Organic phase saturated sodium-chloride washs, and merges organic phase and uses anhydrous MgSO4Being dried, then remove solvent under reduced pressure, obtain thick product, column chromatography purifies, and eluant, eluent is ethyl acetate: petroleum ether (1:10), obtains 6.54g target product, yield 87.2%.
Check Digit Verification of cas no
The CAS Registry Mumber 5422-88-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,4,2 and 2 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 5422-88:
(6*5)+(5*4)+(4*2)+(3*2)+(2*8)+(1*8)=88
88 % 10 = 8
So 5422-88-8 is a valid CAS Registry Number.

Multi N-heterocyclic carbene(NHC)-modified iridium catalysts were employed in the β-alkylation of alcohols; dimerization of primary alcohols (Guerbet reaction), cross-coupling of secondary and primary alcohols, and intramolecular cyclization of alcohols. Mechanistic studies of Guerbet reaction, including kinetic experiments, mass analysis, and density functional theory (DFT) calculation, were employed to explain the fast reaction promoted by bimetallic catalysts, and the dramatic reactivity increase of monometallic catalysts at the late stage of the reaction.

A novel Ni/photoredox-catalyzed acylation of aliphatic substrates, including simple alkanes and dialkyl ethers, has been developed. The method combines C-N bond activation of amides with a radical relay mechanism involving hydrogen-atom transfer. The protocol is operationally simple, employs bench-stable N -acyl imides as acyl-transfer reagents, and permits facile access to alkyl ketones under very mild conditions.
