Electrophilic substitution at saturated carbon. XLIII. Alkylammonium carbanide ion-pair reorganization reactions in base-catalyzed 1,3-proton transfer in an indene system
A new protocol for the deoxygenation of alcohols and the hydrogenation of alkenes under Brønsted acid catalysis has been developed. The method is based on the use of either a benzyl or isopropyl ether as a tracelesshydrogen‐atom donor, and involves an intramolecular hydride transfer as a key step, which is achieved in a regio‐ and stereoselective manner.
