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

Abstract

The oxidation of alcohols to carbonyl compounds is one of the most fundamental reactions in synthetic organic chemistry. In order to achieve the realization of dehydrogenation reactions with high atomic efficiency, suitable catalysts and oxidants are considered as the key factors to obtain the optimum activity and aldehydes/ketones selectivity. This review aims to make an overview on the reasonable reaction mechanism and promising catalytic system of alcohols dehydrogenation.

Ag-Based Catalysts in Heterogeneous Selective Oxidation of Alcohols: A Review

“…Many effective catalytic composites were proposed for selective oxidation of alcohols [1][2][3][4], including those based on individual noble metals (Au [5][6][7], Pd [7], Pt [8], Ru [9], Cu [9], Ir [9], etc.) and bimetallic compositions (e.g., [7]).…”

A Photo-Enzymatic Cascade to Transform Racemic Alcohols into Enantiomerically Pure Amines

“…Various approaches have been reported to selectively oxidize alcohols to the corresponding carbonyl products [10][11][12][13]. Compared to transition metal-based approaches [14], photooxidation provides an atom-economic and environmentally benign alternative [10]. Commercially available TiO 2 is used most commonly as a photocatalyst, but the applicability is restricted by its UV absorption [15].…”

Salep as a biological source for the synthesis of biochar with utility for the catalysis

“…As oxidation of alcohol can lead to two main products, i.e. aldehydes and acids, development of selective protocol is of great importance . On the other hand, due to the increasing environmental concerns, the methodologies that proceed in aqueous media in the presence of molecular oxygen as oxidant and heterogeneous supported metals as catalysts have received much attention …”
