Abstract

original image

Without acception: Acetals are selectively obtained from acceptorless alcohol dehydrogenation (AAD) of aliphatic primary alcohols catalyzed by a ruthenium complex bearing an acridine-based PNP pincer ligand. This unprecedented reaction represents a new tool for one-step acetal synthesis under mild reaction conditions and demonstrates that AAD selectivity can be controlled by changes to the catalyst ligand sphere.
