  • Patent number: 9988339
    Abstract: One embodiment of the invention provides polyisobutylene (PIB) oligomers that are end-functionalized with ruthenium (Ru) catalysts. Such nonpolar catalysts can be dissolved in nonpolar solvents such as heptane, or any other nonpolar solvent that is otherwise not latently biphasic (i.e., if two or more solvent components are present, they remain miscible with each other throughout the entire reaction process, from the addition of substrate through to the removal of product). Substrate that is dissolved in the nonpolar solvent with the catalyst is converted into product. The lower solubility of the product in the nonpolar solvent renders it easily removable, either by extraction with a more polar solvent or by applying physical means in cases where the product precipitates from the nonpolar solvent. In this manner the catalysts are recycled; since the catalysts remain in the nonpolar solvent, a new reaction can be initiated simply by dissolving fresh substrate into the nonpolar solvent.

  • Publication number: 20140142263
    Abstract: Disclosed herein is a first example of effective direct position specific C—H arylation of thieno[3,4-b]pyrazine derivative and several hetero aryl bromide under the ‘Heck-type’ experiment condition using Pd(OAc)2/n-Bu4NBr as a catalyst system, thienopyrazine in which aryl is replaced to increase various values. The current synthesis methodology is a simpler method than a facial method and is used to prepare ?-conjugated oligomer and/or polymer material based on interesting hexylthiophen and thienopyrazine portion for electronic industries which construct a new synthetic organic material using potential application programs. The arylation generates more position selectivity in a C—H bond than in a pyrazine C—H bond. The optical and electrical characteristics of the synthesis copolymer are survey.
