97250-26-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 97250-26-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,2,5 and 0 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 97250-26:
(7*9)+(6*7)+(5*2)+(4*5)+(3*0)+(2*2)+(1*6)=145
145 % 10 = 5
So 97250-26-5 is a valid CAS Registry Number.

Rhodium-Catalyzed Remote C(sp3)?H Borylation of Silyl Enol Ethers

Li, Jie,Qu, Shuanglin,Zhao, Wanxiang

supporting information, p. 2360 - 2364 (2020/01/02)

A rhodium-catalyzed remote C(sp3)?H borylation of silyl enol ethers (SEEs, E/Z mixtures) by alkene isomerization and hydroboration is reported. The reaction exhibits mild reaction conditions and excellent functional-group tolerance. This method is compatible with an array of SEEs, including linear and branched SEEs derived from aldehydes and ketones, and provides direct access to a broad range of structurally diverse 1,n-borylethers in excellent regioselectivities and good yields. These compounds are precursors to various valuable chemicals, such as 1,n-diols and aminoalcohols.

Addition reaction of arylboronic acids to aldehydes and α,β-unsaturated carbonyl compounds catalyzed by conventional palladium complexes in the presence of chloroform

Yamamoto, Tetsuya,Iizuka, Michiko,Takenaka, Hiroto,Ohta, Tetsuo,Ito, Yoshihiko

experimental part, p. 1325 - 1332 (2009/09/28)

Arylboronic acids react with aldehydes and α,β-unsaturated carbonyl compounds in the presence of a base and a catalytic amount of a palladium(0) complex with chloroform, affording the corresponding addition products in good yields, and chiral benzhydrol was obtained with up to 43% e.e. using (S,S)-bppm as a ligand. General palladium complexes have no catalytic activity without chloroform. Because chloroform is essential for this reaction, these reactions would be promoted by dichloromethylpalladium(II) species.

Palladium-catalyzed enantioselective conjugate addition of arylboronic acids

Gini, Francesca,Hessen, Bart,Minnaard, Adriaan J.

, p. 5309 - 5312 (2007/10/03)

(Chemical Equation Presented) The first asymmetric palladium-catalyzed conjugate addition of arylboronic acids to α,β-unsaturated aldehydes, ketones, and esters is described. For cyclic substrates, excellent chemo-, regio-, and enantioselectivities are achieved when a Pd(O2CCF 3)2/DuPHOS catalyst is applied.
