1. ChemInform Abstract: An Extremely Facile Synthesis of Furans, Pyrroles, and Thiophenes by the Dehydrative Cyclization of Propargyl Alcohols

Author

Aaron Aponick, Jeremy Malinge, Chuan‐Ying Li, and Emerson Finco Marques

Subjects
Chemistry, Propargyl, Organic chemistry, General Medicine, Thiophene derivatives, Pyrrole derivatives, Catalysis
Abstract

Furans, pyrroles, and thiophenes are efficiently prepared by gold-catalyzed dehydrative cyclizations of readily available, heteroatom-substituted propargylic alcohols. The reactions are rapid, high-yielding, and procedurally simple, giving essentially pure aromatic heterocycles in minutes under open-flask conditions with catalyst loadings as low as 0.05 mol %.

Abstract

Luminescent hybrid silica nanoparticles grafted with tetrazines fluorophores have been synthesized and characterized, and their photophysical and electrochemical properties have been studied in acetonitrile solutions. The photophysical behavior of the functionalized nanoparticles shows a bright fluorescence emission, with emission and excitation bands typical of chloroalkoxytetrazines fluorophores, albeit with some degree of quenching because of interchromophoric interactions. Their fluorescence emission properties have been studied in the presence of various low molecular weight amines. Extinction of the fluorescence of the nanoparticles because of photoinduced electron transfer between the photoexcited tetrazine and the amine is observed, making these functionalized nanoparticles potentially useful for amine sensing.
