Selective Mono- and Bis(alkoxycarbonylation)s of Olefins Catalyzed by Palladium in the Presence of Cu(I) or Cu(II) Chloride under Remarkably Mild Conditions. Application to the Synthesis of γ-Butyrolactone Derivatives
Palladium-catalyzed mono- and bis(alkoxycarbonylation)s of olefins were controlled by the use of copper(II) and copper(1) chloride, respectively, in alcohol under normal pressure of carbon monoxide and oxygen at room temperature without any other additives. 3-Buten-1-ols gave the corresponding γ-butyrolactones and 2-oxotetrahydrofuran-3-acetic acid esters, respectively, in high yields.

The invention provides a polymer comprising an acid cured solvented resole wherein the solvented resole is substantially free from water; a shaped article formed from the polymer and use of the polymer as an electrode, as an electromagnetic shielding material, to suppress electromagnetic interference, or to prevent electrostatic discharge at a location; which polymer is conductive.
