Acrylate - Wikipedia

https://en.wikipedia.org/wiki/Acrylate
Acrylates (IUPAC: prop-2-enoates) are the salts, esters, and conjugate bases of acrylic acid.The acrylate ion is the anion CH 2 =CHCO − 2.Often, acrylate refers to esters of acrylic acid, the most common member being methyl acrylate.These acrylates contain vinyl groups.These compounds are of interest because they are bifunctional: the vinyl group is susceptible to polymerization and the

Acylation - Wikipedia

https://en.wikipedia.org/wiki/Acylation
In chemistry, acylation is a broad class of chemical reactions in which an acyl group (R−C=O) is added to a substrate.The compound providing the acyl group is called the acylating agent.The substrate to be acylated and the product include the following: alcohols, esters; amines, amides; arenes, ketones; A particularly common type of acylation is acetylation, the addition of the acetyl group.

Normally, a stoichiometric amount of the Lewis acid catalyst is required, because both the substrate and the product form complexes. The Friedel-Crafts Alkylation may give polyalkylated products, so the Friedel-Crafts Acylation is a valuable alternative. The acylated products may easily be converted to the corresponding alkanes via Clemmensen

The peak wavelengths for the different curcumin acrylate species are listed in Table 1. The UV-vis absorbance peaks shift to lower wavelengths due to acrylation, with the curcumin peak maximum at approximately 420 nm, monoacrylates at 410 nm, diacrylates around 400 nm, and triacrylates at 370 nm. Figure 3.

Acylation is an alternative to silylation and it retains some of the advantages of silylation, such as the creation of less polar and more volatile derivates. However, it excludes derivatizing attack on most carboxylic acid and carboxylic acid-like functional groups. Acylation reagents more readily target polar multi-functional compounds such as carbohydrates and amino acids and, in so doing

Friedel-Crafts acylation follows a similar mechanism as the alkylation with the first step being activation of the acyl halide. The resulting product places a carbonyl group next to the aromatic ring. The goal of the reaction is the following: The very first step involves the formation of the acylium ion which will later react with benzene:

On the other hand, acrylation of vegetable oils has been generally carried out as a two-step process consisting in an initial epoxidation reaction (as explained above), followed by acrylation using acrylic acid. This is the common way of obtaining acrylated epoxidized vegetable oils, such as the ones made of soybean, palm,

Curcumin Acrylation for Biological and Environmental Applications

https://pubs.acs.org/doi/10.1021/acs.jnatprod.6b00951
Curcumin has recently gained interest for use in drug delivery, chemical sensing, and environmental applications. As a result, the development of synthesis strategies for the incorporation of curcumin into novel materials has become a priority. One such strategy, curcumin acrylation, involves the introduction of acrylate functional groups to the curcumin scaffold, with the potential generation

Either way, but it's a very similar mechanism. And actually, what we're going to show in this video is called Friedel-Crafts acylation, because this right here is called an acyl group and we're essentially going to acylate the benzene ring. We're going to add this group right here to the benzene ring.

The acrylate ion [CH2=CHCOO]- is the conjugate base of acrylic acid. Acrylates are the salts and esters of acrylic acid. They are also known as propenoates (since acrylic acid is also known as 2-propenoic acid). Acrylates contain vinyl groups, that is, two carbon atoms double bonded to each other, directly attached to the carbonyl carbon.

Acylation refers to the addition of lipophilic acids to the N-terminus or amino acid side chain amine (N-acylation) or cysteine (S-acylation) residue of the peptide. Naturally occurring AMPs having fatty acid linked to the N-terminus of peptides are known as lipopeptaibols. Synthetically, many groups have generated acylated variants of lactoferricin B, magainin, LL-37, mastoparan-X, etc., and
