127236-74-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 127236-74-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,2,3 and 6 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 127236-74:
(8*1)+(7*2)+(6*7)+(5*2)+(4*3)+(3*6)+(2*7)+(1*4)=122
122 % 10 = 2
So 127236-74-2 is a valid CAS Registry Number.

Addition of Diazo Compounds ipso -C-H Bond to Carbon Disulfide: Synthesis of 1,2,3-Thiadiazoles under Mild Conditions

Zhang, Lei,Sun, Beiqi,Liu, Qianyi,Mo, Fanyang

, p. 4275 - 4278 (2018)

We describe here an operationally simple and straightforward synthesis method for a series of diverse 4,5-disubstituted 1,2,3-thiadiazoles via the nucleophilic addition of α-diazo carbonyl compounds to carbon disulfide. This method features using abundant and inexpensive carbon disulfide under mild reaction conditions.

Enantioselective Copper-Catalyzed Oxy-Alkynylation of Diazo Compounds

Hari, Durga Prasad,Waser, Jerome

, p. 8420 - 8423 (2017/07/06)

Enantioselective catalytic methods allowing the addition of both a nucleophile and an electrophile onto diazo compounds give a fast access into important building blocks. Herein, we report the highly enantioselective oxyalkynylation of diazo compounds usi

Catalyzed addition of diazoacetoacetates to imines: Synthesis of highly functionalized aziridines

Zhang, Xue-Jing,Yan, Ming,Huang, Dan

experimental part, p. 187 - 192 (2009/04/07)

The addition of diazoacetoacetates to aromatic imines derived from p-methoxyaniline is achieved using dirhodium tetraacetate as the catalyst. Highly functionalized aziridines are obtained in good yield and with excellent stereoselectivity. 2-Diazo-1,3-diketones also provide good yields of aziridines, but dimethyl diazomalonate is inactive in the transformation. The diazoacetoacetates of chiral alcohols are also examined in the reaction and moderate diastereoselectivity is achieved with (R)-pantolactone-derived diazoacetoacetate. A reaction mechanism through metal-carbene and azomethine ylide is proposed.
