Hydroxyl Assisted, Photoredox/Cobalt Co-catalyzed Semi-Hydrogenation and Tandem Cyclization of o-Alkynylphenols for Access to 2,3-Dihydrobenzofurans

Herein, a hydroxyl assisted, photoredox/cobalt co-catalyzed semi-hydrogenation and tandem cyclization of o-alkynylphenols is developed towards direct assembly of 2,3-dihydrobenzofurans. Moderate to good yields were obtained for a range of sterically and electronically diverse 2-propynolphenols under mild conditions. Mechanistic studies demonstrated the inevitable role of the alcoholic hydroxyl group with (Z)-alkene as the real intermediate. Finally, a key low-valent cobalt catalyzed intramolecular hydroetherification of alkene is proposed. (Figure presented.).

HBF4-Catalysed Nucleophilic Substitutions of Propargylic Alcohols

The activity of HBF4 (aqueous solution) as a catalyst in propargylation reactions is presented. Diverse types of nucleophiles were employed in order to form new C-O, C-N and C-C bonds in technical acetone and in air. Good to excellent yields and good chemoselectivities were obtained using low acid loading (typically 1 mol-%) under simple reaction conditions.
