A halogen bond donor based on a 2,2’-bipyridine framework has been synthesized, and used to catalyze Friedel?Crafts reactions of furans. Electrophiles used successfully in these reactions included various enones, an aldehyde, and a carboxylic acid anhydride. The yields of the reactions were generally good using a moderate catalyst loading (0.025 or 0.1 equiv.) at a relatively low temperature (room temp. or 50 °C) in acetonitrile. The catalyst used was designed with a biaryl scaffold so that if it indeed proved to be an efficient halogen bond donor organocatalyst, an enantioenriched version of it could potentially serve as a stereoselective catalyst.

Alkylation of heteroarenes by using aldehydes is a direct approach to increase molecular complexity, which however often involves the use of stochiometric oxidant, strong acid, and high temperature. This study concerns an energy-efficient electrochemical alkylation of heteroarenes by using aldehydes under mild conditions without mediators. Interestingly, the graphite anode can trigger aldehyde cationic species, which act as the effective autocatalysts to react with a range of heteroarenes to produce the corresponding products with excellent regioselectivity and in high yields. Compared to the traditional electro-synthesis approaches, this electro-triggered reaction provides an electricity-saving and eco-friendly route to high-value chemicals.
