HPLC of Formula: 1530-32-1In 2022 ,《Contra-thermodynamic Olefin Isomerization by Chain-Walking Hydroboration and Dehydroboration》 was published in Organic Letters. The article was written by Hanna, Steven; Bloomer, Brandon; Ciccia, Nicodemo R.; Butcher, Trevor W.; Conk, Richard J.; Hartwig, John F.. The article contains the following contents:
Dehydroboration is coupled with chain-walking hydroboration to create a one-pot, contra-thermodn., short- or long-range isomerization of internal olefins to terminal olefins. This dehydroboration occurs by a sequence comprising activation with a nucleophile, iodination, and base-promoted elimination. The isomerization proceeds at room temperature without the need for a fluoride base, and the substrate scope of this isomerization is expanded over those of previous isomerizations authors have reported with silanes. In the experiment, the researchers used many compounds, for example, Ethyltriphenylphosphonium bromide(cas: 1530-32-1HPLC of Formula: 1530-32-1)
Ethyltriphenylphosphonium bromide(cas: 1530-32-1) is a phase transfer catalyst, used to accelerate the cure of phenolic-based epoxy resins, certain fluoroelastomer resins and thermosetting powder coatings. CatOnium ETPB is also used as catalysts in the synthesis of certain organic compounds.HPLC of Formula: 1530-32-1
