270921-38-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 270921-38-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,7,0,9,2 and 1 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 270921-38:
(8*2)+(7*7)+(6*0)+(5*9)+(4*2)+(3*1)+(2*3)+(1*8)=135
135 % 10 = 5
So 270921-38-5 is a valid CAS Registry Number.

Light-induced synthesis of unsymmetrical organic carbonates from alcohols, methanol and CO2under ambient conditions

Saini, Sandhya,Gour, Nand Kishor,Khan, Shafiur Rehman,Deka, Ramesh Chandra,Jain, Suman L.

supporting information, p. 12800 - 12803 (2021/12/13)

The present work describes the first visible light-assisted, metal-free and organic base 1,1,3,3-tetramethyl guanidine (TMG) mediated synthesis of unsymmetrical methyl aryl/alkyl carbonates from the reaction of alcohols, methanol, and CO2 in high to excel

Cleavage of C–C and C–O Bonds to Form C–C Bonds: Direct Cross-Coupling between Acetylenic Alcohols and Benzylic Carbonates

Mi, Zhiyuan,Tang, Jiahao,Guan, Zhipeng,Shi, Wei,Chen, Hao

supporting information, p. 4479 - 4482 (2018/09/10)

A palladium-catalyzed cross-coupling reaction between C(sp) and C(sp3) centers was achieved in excellent yields via C–C bond cleavage and C–O bond cleavage. This procedure uses relatively stable acetylenic alcohols as reactants instead of unsta

A general Pd-catalyzed α- And γ-benzylation of aldehydes for the formation of quaternary centers

Franzoni, Ivan,Guénée, Laure,Mazet, Clément

supporting information, p. 6338 - 6343 (2015/06/08)

A palladium-catalyzed benzylation of α-branched aldehydes has been developed using benzyl methyl carbonates. The method gives access to congested quaternary centers in the vicinity of one of the most sensitive carbonyl functionalities and displays unprecedented generality with respect to both coupling partners. Evidence for the direct involvement of a Pd-η3-benzyl intermediate is provided. Extension of this strategy to the γ-benzylation of α,β-unsaturated aldehydes is further demonstrated.
