Bowl-Shaped Tris(2,6-diphenylbenzyl)tin Hydride: A Unique Reducing Agent for Radical and Ionic Chemistry

Abstract

Unique selectivity, hitherto not observable in ordinary radical and ionic reactions, is achieved with the bowl‐shaped tris(2,6‐diphenylbenzyl)tin hydride (TDTH; see structure), which has been successfully utilized as a new reducing agent.

Palladium-Catalyzed Three-Component Cascade Carbonylation Reaction to Construct Benzofuran Derivatives

“…In 2021, Lautens’ group reported the Pd-catalyzed cyclization reaction of aryl active reagents tethering alkyne compounds (Scheme a), followed by Lewis acid-catalyzed isomerization to prepare benzofuran derivatives. Although many similar cyclization strategies have been reported, studies of the one-pot preparation of benzofuran skeletons and the introduction of reactive functional groups are still relatively rare …”
