1. Electrochemically Generated Benzyl Cation‐Triggered Alkylacetoxylation of Terminal Alkynes with (Thio)xanthenes and Carboxylic Acids.

Abstract

A catalyst‐free electrochemical alkylacetoxylation reaction of terminal alkynes with (thio)xanthenes and carboxylic acids is developed. Treating the addition products with K2CO3 as a base in methanol affords the ketones in moderate to good yields. Preliminary experimental and computational studies indicate that the benzylic cation generated from the (thio)xanthenes triggers the electrophilic addition to alkynes. [ABSTRACT FROM AUTHOR]

Abstract

A dehydrogenative oxygenation of C( sp2)H bonds with intramolecular phenolic hydroxy groups has been developed, which provides a straightforward and concise access to structurally diversely benzofurans from ortho-alkenylphenols. The reaction is catalyzed by palladium on carbon (Pd/C) without any oxidants and sacrificing hydrogen acceptors. [ABSTRACT FROM AUTHOR]
