The author of 《Rhenium-Catalyzed Regioselective ortho-Alkenylation and [3 + 2 + 1] Cycloaddition of Phenols with Internal Alkynes》 were Murai, Masahito; Yamamoto, Masaki; Takai, Kazuhiko. And the article was published in Organic Letters in 2019. COA of Formula: C7H8O2 The author mentioned the following in the article:
An operationally simple and direct rhenium-catalyzed ortho-alkenylation (C-alkenylation) of unprotected phenols with alkynes was developed. The protocol provided ortho-alkenylphenols exclusively, and formation of para- or multiply alkenylated phenols and hydrophenoxylation (O-alkenylation) products were not observed The [3 + 2 + 1] cycloaddition of phenols and two alkynes via ortho-alkenylation was also demonstrated, in which the alkynes functioned as both two- and one-carbon units. These reactions proceeded with readily available starting materials under neutral conditions without addnl. ligands. In the experimental materials used by the author, we found m-Methoxyphenol(cas: 150-19-6COA of Formula: C7H8O2)
m-Methoxyphenol(cas: 150-19-6) may be used as an analytical standard for the determination of the analyte in wine, coffee beans, wood samples, and mainstream smoke by gas chromatography (GC) based techniques.COA of Formula: C7H8O2
