in the ligand are crucial for the activity of catalyst and selective transfer hydrogenation is the determining step of the formation of alkenyl ketones as products. Notably, the present research exhibited also the unique potential of metal–ligand bifunctional catalysts for the activation of unsaturated alcohols as electrophiles for hydrogen auto-transfer process.

The borrowing hydrogen approach allows the direct utilization of non-activated alcohols as alkylating agents. A readily available, air and moisture stable ruthenium complex proves to be a particularly effective hydrogen autotransfer catalyst for the alkylation of various indoles or ketones with poorly reactive alcohols.
