Iwamoto, Hiroaki; Tsuruta, Takuya; Ogoshi, Sensuke published their research in ACS Catalysis in 2021. The article was titled 《Development and Mechanistic Studies of (E)-Selective Isomerization/Tandem Hydroarylation Reactions of Alkenes with a Nickel(0)/Phosphine Catalyst》.Recommanded Product: Ethyltriphenylphosphonium bromide The article contains the following contents:
A stereoselective alkene isomerization and sequential hydroarylation with arylboronic acid using a nickel(0) catalyst was developed. The bulky monophosphine PAd2(n-Bu) was an effective ligand in these reactions to furnish both various stereo-defined internal alkenes and hydroarylation products (isomerization: up to 98%, E/Z = 98:2; tandem hydroarylation: up to 82%). Mechanistic studies based on experiments and computational calculations suggested that the isomerization proceeds via an intra- or intermol. hydrogen shift. Furthermore, a concerted multibond recombination with boronic acid-assisted oxidative protometallation of the alkene were found to be a reasonable mechanism for the formation of the alkylnickel(II) species from the alkene, nickel(0), alc., and boronic acid in the hydroarylation. After reading the article, we found that the author used Ethyltriphenylphosphonium bromide(cas: 1530-32-1Recommanded Product: Ethyltriphenylphosphonium bromide)
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. It is also used as catalysts in the synthesis of certain organic compounds and as a pharmaceutical intermediate.Recommanded Product: Ethyltriphenylphosphonium bromide
