178889-49-1 Usage
General Description
1-Methylcyclopentyl Acrylate is a type of organic compound that falls under the category of acrylates, which are salts or esters of acrylic acid. This chemical is particularly used in the manufacture of polymers, providing them with different properties, such as weatherability, heat resistance, flexibility, and adhesion, according to application needs. It is important to note that acrylates, including 1-Methylcyclopentyl Acrylate, may cause skin and eye irritation and may have harmful effects if inhaled or swallowed, so handling with appropriate protective measures is necessary. However, when used correctly in various industrial processes, this chemical can significantly enhance product performance.
Check Digit Verification of cas no
The CAS Registry Mumber 178889-49-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,8,8,8 and 9 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 178889-49:
(8*1)+(7*7)+(6*8)+(5*8)+(4*8)+(3*9)+(2*4)+(1*9)=221
221 % 10 = 1
So 178889-49-1 is a valid CAS Registry Number.

Catalytic acryloxypalladation of vinylcycloalkanes and exo-methylene cycloalkanes. Mechanistic insights into the competition between allylic acryloxypalladation and formation of a-methylene y-butyrolactones

Acryloxypalladation of ezo-methylenecycloalkanes (three-, four-, five- and six-membered rings) and vinylcycloalkanes (three-, five- and six-membered rings) in the presence of the Pd(OAc)2/p-benzoquinone/MnC>2 catalytic system is reported. Except for the case of eio-methylenecyclopropane, this reaction provides a rapid entry to the corresponding Q-metliylene -/-butyrolactone, which essentially results from a 1,2-Markovnikov acryloxypalladation addition on the double bond. The subsequent insertion of the acrylate double bond into the carbon-palladium bond is followed by a β-elimination step. However, this reaction competes with the formation of intermediate -allyl complexes which yields the corresponding allylic acrylates. The ratio of butyrolactones to allylic acrylates is dependent on ring size. Elsevier,.
