122590-90-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 122590-90-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,2,5,9 and 0 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 122590-90:
(8*1)+(7*2)+(6*2)+(5*5)+(4*9)+(3*0)+(2*9)+(1*0)=113
113 % 10 = 3
So 122590-90-3 is a valid CAS Registry Number.

Preparation of 1-aryl-2,2-difluoro enol esters via dehydrosulfonylation of α-(phenylsulfonyl)difluoromethylated benzoates

Zhang, Laijun,Li, Ya,Hu, Jinbo

, p. 755 - 761 (2007)

1-Aryl-2,2-difluoro enol benzoates 4 has been prepared from α-(phenylsulfonyl)-difluoromethylated benzoates 3, which can be readily obtained from the reactions between simple aldehydes and PhSO2CF2H (or TMSCF2SO2/sub

Nucleophilic difluoro(phenylsulfonyl)methylation of carbonyls with PhSO2CF2H reagent in the presence of in situ generated substoichiometric amount of base Dedicated to Professor Iwao Ojima on the occasion of his receipt of the ACS Aw

, p. 52 - 58 (2013/10/01)

The reactions between carbonyl compounds and PhSO2CF 2H using substoichiometric amount of base in situ generated from N(TMS)3 and catalytic amount of Me4NF have been investigated. It is found that both enolizabl

Process for nucleophilic fluoroalkylation of aldehydes

, (2008/06/13)

Aryl difluoromethyl sulfone adds to alkehydes under phase transfer conditions to give novel substituted alcohols of the general formula wherein R is an aryl, cycloaliphatic, sec- or tert-aliphatic, or heterocyclic group and Ar is an aryl group. The substituted alcohols of formula I are of particular utility as intermediates in the synthesis of a variety of useful end products. For example, the products of formula I may be utilized in desulfonylation reactions, oxidation reactions and fluorination reactions.
