A new impregnated iridium on magnetite catalyst has been prepared, characterized, used and recycled, up to ten times with practically the same activity, for the first practical cross-alkylation of primary alcohols. The catalyst showed a wide reaction scope, is easy to prepare and handle, and it could be removed from the reaction medium just by magnetic sequestering.

A simple method has been developed for the cross dehydrogenative coupling between two different primary alcohols using readily available RuCl2(PPh3)3 as a precatalyst through the borrowing-hydrogen approach. The present methodology is applicable to a large variety of alcohol derivatives including long chain aliphatic alcohols and heteroaryl alcohols. In addition, the methodology was applied in a straightforward
their well-explored propensity to undergo ring-opening reactions with nucleophiles. However, their application as precursors of radical species is still elusive. Herein, we present a bioinspired cobalt-catalysis-based strategy to access unprecedented modes of radical reactivity via oxetane ring-opening. This powerful approach gives access to nucleophilic radicals that engage in reactions with SOMOphiles
