These polymers exhibit unique properties, such as self-healing capabilities, which can be beneficial in various applications, including coatings, adhesives, and electronic devices.
Used in Pharmaceutical Industry:
4-Vinylphenylboronic acid is used as a precursor in the synthesis of aggregation-induced emission (AIE) dyes. These dyes have potential applications in the development of new drugs, as they can be used to study the behavior of molecules in different environments, such as in the presence of proteins or other biological molecules.
Used in Suzuki Reaction:
4-Vinylphenylboronic acid is also commonly used in the Suzuki reaction, a widely employed method for the formation of carbon-carbon bonds in organic synthesis. The Suzuki reaction is particularly useful in the production of complex organic molecules, such as pharmaceuticals and agrochemicals, where the formation of specific carbon-carbon bonds is crucial.
Check Digit Verification of cas no
The CAS Registry Mumber 2156-04-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,5 and 6 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 2156-04:
(6*2)+(5*1)+(4*5)+(3*6)+(2*0)+(1*4)=59
59 % 10 = 9
So 2156-04-9 is a valid CAS Registry Number.

Styrylboronic acid, C8H9BO2, was one of several organoboron compounds investigated for their woodpreservation properties following in situ polymerization.The structure consists of independent monomeric molecules bound together by strong hydrogen bonds (B-O-H...O).The planes of the styryl and boronic acid moieties are twisted by 26(1) deg with respect to each other, apparently as a result of the hydrogen-bonding requirements.onance interaction with the thioester groups.
Hantzsch Ester as a Photosensitizer for the Visible-Light-Induced Debromination of Vicinal Dibromo Compounds

The debromination of vicinal dibromo compounds to generate alkenes usually requires harsh reaction conditions and the addition of catalysts. Just recently the visible-light-induced debromination of vicinal dibromo compounds emerged as a possible alternative to commonly used methods, but the substrate scope of this reaction is limited and a photocatalyst is necessary for the successful conversion of the starting compounds. A catalyst-free visible-light-induced debromination of vicinal dibromo compounds with a base-activated Hantzsch ester as photosensitizer is reported. The method has a wide substrate scope and a broad functional-group compatibility.
Systematic investigation of ligand substitution effects in cyclophane-based nickel(II) and palladium(II) olefin polymerization catalysts
Popeney, Chris S.,Levins, Chris M.,Guan, Zhibin
experimental part, p. 2432 - 2452 (2011/06/22)
The synthesis of Ni(II) and Pd(II) cyclophane-based α-diimine olefin polymerization catalysts bearing a range of electron-donating or -withdrawing groups is described. Substituent effects were confirmed by measurement of CO infrared stretching frequencies
