Cobalt-catalyzed dehydrogenative functionalization of alcohols: Progress and future prospect

Well-Defined Phosphine-Free Manganese(II)-Complex-Catalyzed Synthesis of Quinolines, Pyrroles, and Pyridines

“…Recently, base-metal Co, Ni, and Fe complexes have been well explored for the synthesis of several N-heterocycles following the ADC concept utilizing alcohols. Additionally, Mn­(I) complexes were also well documented in the literature for similar transformations.…”

Acceptorless dehydrogenation of alcohols to carboxylic acids by palladium nanoparticles supported on NiO: delving into metal–support cooperation in catalysis

“…Hence, over the past few years, efforts have been made to design sustainable heterogeneous catalysts for AD reactions, mainly based on noble metals like Rh, 29 Pd, [30][31][32] Pt, 33 Ag, 34 etc. Due to easy accessibility and low cost, non-noble metal-based heterogeneous catalysts namely Fe, 35 Co, 4,[36][37][38] Ni, 39,40 Cu, 41,42 etc. have also been investigated for this reaction.…”

A general and practical bifunctional cobalt catalytic system for N-heterocycle assembly via acceptorless dehydrogenation

“…Recently, research studies [19][20][21][22][23] and reviews [24][25][26] have been reported in the field of cobalt complex catalyzed AD reactions for N-heterocycle synthesis (Scheme 2, top), which are important breakthroughs compared to noble-metal catalysis such as Ir and Ru catalysis. 27,28 In 2016, Milstein and coworkers reported a Co-PNNH catalyst for pyrrole synthesis via ADC of diols and amines.…”
