Mercuric Acetate styrene with

The arylation of enol esters has also been improved (95). Previously a wide range of products were produced including j8-aryl carbonyls, arylated enol esters, styrene, and stilbene derivatives (96). It has also been found that arylated enol esters can be obtained as major products if the reactions are carried out with stoichiometric amounts of aryl mercuric acetate and palladium acetate in anhydrous acetonitrile or in excess enol ester solution. The products are those arising from addition of the phenyl group to the carbons not containing the ester. Thus, with vinyl acetate and phenyl mercuric acetate, the product is the enol acetate of phenyl acetaldehyde ... 

Problem 15.8 Predict the product of the reaction of styrene with mercuric acetate in methanol solution, followed by reduction with NaBH4. 

Phosphonate analogues of Reissert compounds (76) have been prepared and converted into 1-alkyl-isoquinolines (Scheme 49). Treatment of a number of A -methylisocarbostyrils with mercuric acetate gave rise to 4-mercuri-ated derivatives, which underwent insertion reactions with methyl acrylate and with styrenes in the presence of palladium chloride (Heck reaction). 

Cyclopalladated t-butylimine compounds are reacted with styrene and then treated with trifluoroacetic acid to give o-formylstilbenes in high yields. Their A -methylimine derivatives are converted to another heterocyclic compound, 3-aryl-N-methyl-isoquinolones 7.22, by oxidation with mercuric acetate, as shown in Eq. (7.20) [78]. 

Bbaun and Vobendohbe [7] have carried out TLC of unsaturated polymerisable compoimds which are found also in the p3rrolysis products of high polymers. They chromatographed the addition compounds obtained by reacting 15—20 mg of the monomers with 120 mg mercuric acetate in methanol. Excess mercuric acetate can be reduced with hydrazine without the adducts suffering attack (those of a-methyl-styrene, vinyl acetate, vinylcarbazole and vinyl chloride are unstable... 

Product COSAN PMA-30 is a solubilized phenyl mercuric acetate formulation which has earned acceptance as the highly effective standard in the industry for protecting liquid emulsion systems and films. COSAN PMA-30 is water soluble and compatible with styrene-butadiene, acrylic, vinyl-acrylic, polyvinyl acetate, oil and alkyd modified systems. COSAN PMA-30 will not adversely affect freeze-thaw stability, whites and light tints.
