Whereas an Ir-catalyzed alcohol deoxygenation on basis of dehydrogenation/Wolff-Kishner reduction is efficient mainly with activated alcohols under harsh reaction conditions, a Ru-catalyzed aliphatic primary alcohol deoxygenation offers good functional group tolerance and excellent efficiency under practical reaction conditions. Its synthetic utility is further illustrated by complete chemo- and regio-selectivity in complex molecular settings.
