Benzyl acrylate

Polymer-bound benzyl acrylate REgenerated Michael acceptor) resin... 

Typical nucleophilically cleavable linkers are the REM resin linker 86 [75] (polymer-bound benzyl acrylate regenerated Michael acceptor) and the Dde group 87 (ADCC (4-Acetyl-3,5-dioxo-l-methylcyclohexane carboxylic acid) anchor) [76], which are linkers for tertiary and primary amines, respectively (Figure 6.1.7). 

Se-Ph selenoester is a good precursor of an acyl radical where it behaves as a nucleophilic radical. Treatment of Se-Ph selenoester (20) and benzyl acrylate with Bu3SnH generates a y-keto ester (21) as shown in eq. 4.1 la. 2-Indolylacyl radical can be generated from Se-Ph selenoester (22) by this method (eq. 4.11b) [25-30]. 

Phenyl Crotonic Acid. Phenyl Vinyl Acetic Acid.—A phenyl derivative of crotonic acid is known, CeHs—CH2—CH = CH—COOH, beta-benzyl acrylic add. Also the structural isomer of crotonic acid, viz., vinyl acetic acid, CH2 = CH—CH2—COOH, yields a phenyl derivative, CeHs—CH=CH—CH2—COOH, phenyl vinyl acetic acid or I-phenyl Ai-butenoic-4 acid, which is important in connection with the constitution of naphthalene (p. 768). 

The hydrogenolysis of benzyl protecting groups on poly(benzyl acrylates) and related polymers was successfully accomplished over Pd/C at room temperature and atmospheric pressure provided the palladium was present on the surface of the support and not in the pores.59... 

The product of a Diels-Alder reaction between cyclopentadiene and benzyl acrylate must necessarily be racemic as both reagents are achiral. Though only one diastereoisomer—the endo product—is formed, it must be formed as an exactly 50 50 mixture of enantiomers. 

Specifically mentioned monomers include methyl acrylate, ethyl acrylate, propyl acrylate (all isomers), butyl acrylates (all isomers), 2-ethylhexyl acrylate, isobornyl acrylate, acrylic acid, benzyl acrylate, phenyl acrylate, acrylonitrile, glycidyl acrylate,... 

The methylene unit attached to the ethereal oxygen is particularly reactive towards radical attack and thus chain-transfer processes would be expected to substantially reduce the molecular weight of the final polymer. Some reduction is noticed but both this solvent and toluene can be used for free-radical polymerization (and note the successful polymerization of benzyl acrylate in Protocol 1). 

Benzyl acrylate is then purified by distillation at reduced pressure (b.p. 130-140°C at 20 mmHg) to yield a colourless liquid. This is further purified by column chromatography (on silica gel) to give the monomer in 69% yield. ... 

Place the benzyl acrylate (2 g, 0.012 mol) and AIBN (0.010 g, 6.1 X 10 mol) in a polymerization tube the add chlorobenzene (20 mL). A protective netting sleeve is then placed over the tube to minimize danger from glass, should the tube shatter. Attach the tube to the manifold and close the Young s tap at the top of the tube.
