Recent Advances in C–H Bond Functionalization with Ruthenium-Based Catalysts

Autor: Keisham S. Singh

Publikováno v: Catalysts, Vol 9, Iss 2, p 173 (2019)

The past decades have witnessed rapid development in organic synthesis via catalysis, particularly the reactions through C⁻H bond functionalization. Transition metals such as Pd, Rh and Ru constitute a crucial catalyst in these C⁻H bond functiona

Ruthenium (II)-Catalyzed Transfer Hydrogenation of Aromatic and Heteroaromatic Aldehydes in Air

Autor: Bhosale, Sumit S., Keisham S. Singh

Aromatic and heteroaromatic aldehydes are efficiently reduced to their corresponding alcohols in the presence of [RuCl2(p-cymene)]2 and KOAc in 2-propanol under air at 80 °C. The presence of KOAc in the reaction is essential, in its absence no reduc
