“…36–39 The requirements for more sustainable processes recently also initiated an intensive investigation of alternative catalysts based on earth-abundant, inexpensive 3d metals (Fe, Co, and Mn). 35,40–46 Taking this idea a step further, the transition metal-free catalytic hydrogenation was achieved in the past decade by ‘frustrated Lewis pair’ catalysts but is still in its infancy. 47–54 Although a great amount of hydrogenation catalysts has been developed, understanding the fundamental laws of hydrogenation catalysis that would allow for designing new catalytic systems rationally, remains a central subject in modern catalysis research.…”

“…[47] Indeed, several research groups actively started contributing in the territory of group VI metals-based homogeneously catalyzed (de)hydrogenation reactions. Although few scattered reviews/book chapters on group VI metals catalyzed (ionic)hydrogenation, CO 2 activation are available, [47][48][49][50][51] exclusive review on homogeneous (de)hydrogenation as per best of our knowledge is missing in the repertoire of homogeneous catalysis.…”

Transition metal‐catalyzed homogeneous hydrogenation and dehydrogenation reactions for attaining plethora of organic scaffolds have evolved as a key domain of research in academia and industry. These protocols are atom‐economic, greener, in line with the goal of sustainability, eventually pave the way for numerous novel environmentally benign methodologies. Appealing progress has been achieved in the realm of homogeneous catalysis utilizing noble metals. Owing to their high cost, less abundance along with toxicity issues led the scientific community to search for sustainable alternatives. In this context, earth‐ abundant base metals have gained substantial attention culminating enormous progress in recent years, predominantly with pincer‐type complexes of nickel, cobalt, iron, and manganese. In this regard, group VI chromium, molybdenum and tungsten complexes have been overlooked and remain underdeveloped despite their earth‐abundance and bio‐compatibility. This review delineates a comprehensive overview in the arena of homogeneously catalysed (de)hydrogenation reactions using group VI base metals chromium, molybdenum, and tungsten till date. Various reactions have been described; hydrogenation, transfer hydrogenation, dehydrogenation, acceptorless dehydrogenative coupling, hydrogen auto transfer, along with their scope and brief mechanistic insights.

“…Evolving from the pioneering research that started nearly 30 years ago, 20 various pincer ligands are commonplace in several fields of catalysis, especially those involving hydrogen activation and hydride transfer to polar and unsaturated substrates. 21–24 One of the common explanations of such utility of pincer complexes in catalysis is the ability of some of them to engage in metal–ligand cooperative (MLC) transformations, wherein both the metal and ligand functional groups participate in substrate binding, activation, or conversion (Fig. 1).…”
