Crosslinked Internal Alkyne-Based Stereo Elastomers: Polymers with Tunable Mechanical Properties

New methods to introduce and control polymer network crosslinking and improve mechanical properties of the resulting materials have been investigated extensively. Common methods to enhance the mechanical properties of elastomers include "vulcanization"by

Synthesis, characterization and behavior in water/DMSO solution of Ru(II) arene complexes with bioactive carboxylates

The reactions of [RuCl(μ-Cl)(η6-p-cymene)]2 with sodium carboxylates, in methanol or acetonitrile solution, afforded the complexes [RuCl(κ2O-RCO2)(η6-p-cymene)] (RCO2 = valproate, 1; aspirinate, 2; diclofenate, 3), in 79–96% yields. Analogously, [RuCl(κ2O-dfCO2)(η6-benzene)], 4, was obtained in admixture with minor by-products from [RuCl(μ-Cl)(η6-benzene)]2 and sodium/silver diclofenate. The sequential reaction of [RuCl(μ-Cl)(η6-p-cymene)]2 with sodium salicylate and PPh3 gave [Ru(κ2O,O′-salCO2)(PPh3)(η6-p-cymene)], 5, in 70% yield. The hydride complex [Ru2Cl2(μ-Cl)(μ-H)(η6-p-cymene)2], 6, was produced in 36% yield from [RuCl(μ-Cl)(η6-p-cymene)]2 and sodium formate. An optimization of the experimental work-up allowed to isolate [RuCl(μ-Cl)(η6-p-cymene)]2 with an improved yield respect to the literature (98% vs. 65%). The bidentate coordination mode of the carboxylato ligands in 1–5 was unambiguously ascertained by IR and NMR spectroscopy, moreover the solid state structure of 1 was elucidated by single crystal X-ray diffraction. Complexes 1–3 experience rapid and quantitative dissociation of the carboxylato anion in DMSO/water/NaCl mixtures, mainly converting into [RuCl2(DMSO)(η6-p-cymene)], 7.

Production Of Terephthalic Acid Via Reductive Coupling Of Propiolic Acid Or Propiolic Acid Derivatives

A method of making terephthalic acid via reductive coupling of two molecules of propiolic acid or propiolic acid derivatives is presented. The reductive coupling can be catalyzed by compounds comprising metals, and propiolic acid or propiolic acid derivatives can be produced from acetylene and carbon dioxide. At least 4 of the 8 carbons in the terephthalic acid are non-fossil-derived.

METHODS FOR THE SYNTHESIS OF DEUTERATED ACRYLATE SALTS

A method for synthesizing a deuterated acrylate of the Formula (1), the method comprising: (i) deuterating a propiolate compound of Formula (2) to a methyne-deuterated propiolate compound of Formula (3) in the presence of a base and D2O: and (ii) reductively deuterating the methyne-deuterated propiolate compound of Formula (3) in a reaction solvent in the presence of deuterium gas and a palladium-containing catalyst to afford the deuterated acrylate of the Formula (1). The resulting deuterated acrylate compounds, derivatives thereof, and polymers derived therefrom are also described.

A method for preparing sodium acrylate-d3, a useful and stable precursor for deuterated acrylic monomers

A convenient and economical method for converting propiolic acid to sodium acrylate-d3 is described. Successive D/H exchange of the alkyne proton of sodium propiolate (prepared from propiolic acid) using D2O affords sodium propiolate-d having up to 99 at.% D. Sodium propiolate-d can be partially reduced to sodium acrylate-d3 with 90% conversion and 89% yield using D2 and the Lindlar catalyst, with control of reaction parameters to maximize conversion while minimizing over-reduction. Copyright 2011 John Wiley & Sons, Ltd. A three-step synthetic route for preparing sodium acrylate-d3 in high yield and high isotopic purity from propiolic acid is described. Copyright
