95971-74-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 95971-74-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,5,9,7 and 1 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 95971-74:
(7*9)+(6*5)+(5*9)+(4*7)+(3*1)+(2*7)+(1*4)=187
187 % 10 = 7
So 95971-74-7 is a valid CAS Registry Number.

Method for synthesizing amide compound

-

Paragraph 0234; 0235; 0236, (2018/07/30)

The invention discloses a method for the synthesizing a compound as shown in a formula I which is described in the specification. The method comprises a step of subjecting a compound II, a compound III and a compound IV to reaction in the presence of a catalyst to form the compound as shown in the formula I, wherein the compound II is one selected from compounds as shown in a formula II; the compound III is at least one selected from compounds as shown in a formula III-1 and a formula III-2; the compound IV is one selected from compounds as shown in a formula IV; R3 and R4 are independently selected from a group consisting of an alkyl group, a substituted alkyl group, a heteroaryl group and a substituted heteroaryl group.

An umpolung sulfoxide reagent for use as a functionalized benzyl carbanion equivalent

Pinna, Giovanni,Bellucci, Maria Cristina,Malpezzi, Luciana,Pisani, Laura,Superchi, Stefano,Volonterio, Alessandro,Zanda, Matteo

, p. 5268 - 5281 (2011/08/06)

N-Methyl ortho-carbamoylaryl benzyl sulfoxides can be used as synthetic equivalents for α-hydroxy, α-chloro, and α-acetammido benzyl carbanions by means of a two-step sequence involving highly diastereoselective α-C-alkylation with alkyl halides followed by displacement of the sulfinyl residue (which can be recovered and recycled) by a hydroxyl, a chlorine or an acetamido, respectively, under non-oxidative Pummerer conditions. The scope and limits of the method, including a stereoselective version of the reaction, as well as the mechanism of the process are discussed in detail.

The ritter reaction under truly catalytic bronsted acid conditions

Sanz, Roberto,Martinez, Alberto,Guilarte, Veronica,Alvarez-Gutierrez, Julia M.,Rodriguez, Felix

, p. 4642 - 4645 (2008/03/12)

Simple organic acids like 2,4-dinitrobenzenesulfonic acid (DNBSA) catalyze the Ritter reaction of secondary benzylic alcohols giving rise to the corresponding N-benzylacetamides in usually high yields. Reactions can be conducted without exclusion of oxygen and without the need of dry solvents. With tertiary α,α-dimethylbenzylic alcohols a different pathway involving a formal dimerization reaction takes place under the acid-catalytic conditions used. Wiley-VCH Verlag GmbH & Co. KGaA, 2007.
