Acetylenic sulfones attached to solid supports by means of ester linkers were employed in a variety of cyclization and cycloaddition reactions, followed by cleavage of the products from the resin by ester hydrolysis or reductive desulfonylation.

The title compound, C(21)H(18)O(3)S, is the E isomer, the ester -oxy link being trans to one of the phenyl groups. The planes of the phenyl substituents at the vinyl C atoms form a dihedral angle of 66.32 (7)° with each other. The vinyl group shows noticeable non-planarity, the C(Ph)-C=C-C(Ph) torsion angle being 8.4 (3)°.

Bifunctional phosphinothiourea catalysts have been developed successfully for the highly regio- and enantioselective γ-hydroamination of allenyl and propargyl esters with N-methoxy carbamate nucleophiles to yield α,β-unsaturated γ-amino acid ester products. In the case of propargyl ester substrates, the reaction proceeds through reversible phosphinothiourea-catalyzed isomerization to the corres...

A two-component condensation reaction between an electron-poor acetylenic ester and a phenol e ciently provides substituted aryl vinyl ethers in a one-pot reaction in the presence of dipotassium hydrogen phosphate in solvent-free conditions.

In this research, a method was used to increase the brittleness of unsaturated polyester polymer by mixing it with vinyl ester. The choice ester toughness is because easy form and material has wide applications in engineering. However, several weaknesses, namely, very stiff, brittle, unable withstand cracking loads breaks easily due impact. Polyester rigid nature cross-chain links that are tigh...

a most effective and less energy demanding method of producing fatty esters, diol esters, by esterifying fatty acids, with neopentyl and ethylenglycol alcohols in the presence of an acidic ion exchange resin catalyst(polyestyrendivinylbenzensulfated) was investigated at elevated temperature. in this process an azeotroping agent, toluene, was used to facilitate continuous removal of water by dis...
