General and Selective Palladium‐Catalyzed Oxidative Esterification of Alcohols

Abstract

Selectively esterified: Primary alcohols react with dioxygen as a benign oxidant in a palladium‐catalyzed oxidative esterification (see scheme). The corresponding aldehydes and esters are formed highly selectively depending on the catalyst system. The reactions take place in the presence of commercially available ligands without the need for additional organic hydrogen acceptors.

An Overview of Selective Oxidation of Alcohols: Catalysts, Oxidants and Reaction Mechanisms

“…For example, palladium-catalyzed oxidations with tertiary phosphine oxide (TPO), which have been extensively used in cross coupling reactions, are quite limited [14,15]. Saravanan et al [16] used TPOs as ligands in alcohol oxidations and reported highly selective catalytic oxidation of primary and secondary alcohols to the corresponding carbonyl compounds by utilizing molecular oxygen under mild conditions.…”

Highly efficient self-esterification of aliphatic alcohols using supported gold nanoparticles under mild conditions

“…Among the studies on the catalytic reaction on alcohols, the direct transformation of aliphatic alcohols to corresponding esters has received less attention than that of more reactive benzylic alcohols, as aliphatic alcohols are chemically stable and it is rather challenging to conduct the transformation under mild reaction conditions. To the best of our knowledge, only few examples were reported on the direct self-esterification of aliphatic alcohols [17][18][19][20][21][22][23], while most of these processes result in the corresponding aldehydes and acids as the by-products.…”

“…Previously reported works, mainly homogeneous catalytic systems [17,[24][25][26][27], required harsh reaction conditions such as high temperatures and pressure. In addition, most of these processes have several drawbacks on both environmental and operational aspects, such as employment of toxic metal complexes as catalysts, long reaction time or reusability of catalysts.…”
