42052-51-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 42052-51-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,0,5 and 2 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 42052-51:
(7*4)+(6*2)+(5*0)+(4*5)+(3*2)+(2*5)+(1*1)=77
77 % 10 = 7
So 42052-51-7 is a valid CAS Registry Number.

Novel use of cross-linked poly(N-isopropylacrylamide) gel for organic reactions in aqueous media

Hamamoto, Hiromi,Kudoh, Masahiro,Takahashi, Hideyo,Ikegami, Shiro

, p. 4015 - 4018 (2006)

A poly(N-isopropylacrylamide) (PNIPAAm) gel cross-linked with quaternized aminoalkyls was designed. A novel recyclable system based on the external solvent-responsive oil-absorption/elution transition ability of the PNIPAAm gel matrix was then developed.

Selective Cα-O Bond Cleavage of α,β-Epoxy Ketones to Aldols induced by Free Radical Processes

Hasegawa, Eietsu,Ishiyama, Kenyuki,Horaguchi, Takaaki,Shimizu, Takahachi

, p. 550 - 552 (1990)

Several α,β-epoxy ketones were converted to aldols in good yields upon irradiation or heating with azoisobutyronitrile in the presence of tributyltin hydride in benzene; the reactions involve selective Cα-O bond cleavage of the oxiranylmethyl r

Synthesis method of alpha or beta-substituted aromatic ketone

-

Paragraph 0022-0035, (2021/05/01)

The invention discloses a synthesis method of alpha-or beta-substituted aromatic ketone. The method comprises the following steps: under the condition of inert gas, reacting alpha-oxo-aryl ethanone compounds, B2pin2, PDI-CoCl2 and MBHEt3 in an organic solvent at room temperature, then adding a compound 2, and continuously reacting to obtain a compound 3, wherein in the MBHEt3, M is an alkali metal; the compound 2 is selected from the group consisting of deuterated methanol, Selectfluoro, a TogniII reagent or R2CHO; R2 is an aromatic substituent or alkyl; the organic solvent is an aprotic organic solvent. According to the method, the alpha-oxo aryl ethanone is used as a raw material, a cheap and stable boron reagent and an efficient cobalt catalyst which is cheap and easy to obtain are used, an activating reagent MBHEt3 is added to generate an enol boron ether intermediate, then the enol boron ether intermediate and different electrophilic reagents are synthesized into alpha-or beta-substituted aromatic ketone, the reaction is carried out at normal temperature, and the operation is convenient.

Cellulosic CuI Nanoparticles as a Heterogeneous, Recyclable Catalyst for the Borylation of α,β-Unsaturated Acceptors in Aqueous Media

Zhou, Lijie,Han, Biao,Zhang, Yaoyao,Li, Bojie,Wang, Liansheng,Wang, Jianying,Wang, Xianbao,Zhu, Lei

, p. 3220 - 3229 (2021/03/06)

Abstract: We have demonstrated that cellulosic CuI nanoparticles could perform as an efficient heterogeneous catalyst for the synthesis of useful organoboron compounds. Desired β-borylation products were all obtained in good to excellent yields under mild
