Abstract: Oxidation of alcohols in an oxidant-free condition, commonly known as the acceptorless dehydrogenation (AD) reaction, has recently emerged as
one of the widely used processes in synthetic organic chemistry. Alcohol acts as an excellent chemical precursor that produces a variety of
dehydrogenated value-added products such as carbonyls, acids, acetals, and several coupling products, followed by the concomitant evolution of
molecular hydrogen gas. AD reaction of alcohol, therefore, can be considered as a vital reaction for the hydrogen economy using alcohols as a
liquid hydrogen carrier. Over the past decade, the growing importance of AD reactions has set the way for the continuous development of various
homogeneous and heterogeneous catalytic systems. With the advantage of reusability and recyclability, heterogeneous catalysts have now become
more promising and significant in the catalytic domain. This review aims to make an overview of the transition metal-based heterogeneous
catalytic system of acceptorless alcohol dehydrogenation reaction reported till December, 2023.
