The discovery of a new class of heterocyclic compounds by Pietro Biginelli in 1891 was
regarded as a watershed point in the history of chemistry. Biginelli is a well‐known organic …

A Ru (II)-catalyzed efficient and selective N-alkylation of amines by C1–C10 aliphatic
alcohols is reported. The catalyst [Ru (L1a)(PPh3) Cl2](1a) bearing a tridentate redox-active …

Herein we disclose a series of phosphine-free cobalt (II)-based catalytic systems bearing a
redox non-innocent amine functionalized azo-aromatic pincer-like ligand for the synthesis of …

Transition metal catalysts play a vital role in a wide range of industrial organic processes.
The large-scale production of chemicals relying on catalyzed organic reactions represents a …

Herein, we report a Zn (II)-catalyzed solvent-free sustainable synthesis of tri-and tetra-
substituted pyridines using alcohols as the primary feedstock and NH4OAc as the nitrogen …

The oxygenation processes for the organic compounds have great applications in fine
organic fabrications. To speed up progress in the industrialization of such oxidation systems …

Herein, we report the synthesis and characterization of two ruthenium-based pincer-type
catalysts,[1] X (X= Cl, PF6) and 2, containing two different tridentate pincer ligands, 2 …

Reactivity of transition metal complexes containing the redox-active gallylene (dpp-bian) Ga
ligand (dpp-bian= 1, 2-bis [(2, 6-diisopropylphenyl) imino] acenaphthene) toward …

Transition metal complexes featuring redox-active ligands often exhibit multiple redox states,
influenced by the interplay between the metal center and the ligand. This study delves into …

Treatment of an excess of ytterbium metal with dpp-Bian {dpp-Bian= 1, 2-bis [(2, 6-
diisopropylphenyl) imino] acenaphthene} in the presence of 0.5 equiv of iodine resulted in a …
