efficiently catalyses the reductive N-alkylation of aryl nitrocompounds with alcohols using bio-based glycerol as the hydrogen source and without the need for any added solvents. The reaction can be easily manipulated to produce either imines or secondary amines in high yields. RuCl3-catalyzed reductive N-alkylation of nitroarenes with alcohols affords the corresponding imine products in good to excellent

2-[2-(dimethylamino)pyrimidin-4-yl]pyridine} is highly reactive in catalyzing the reductive amination of aromaticaldehydes through in situ generated imines with 2-propanol as the hydrogen source following a transfer-hydrogenation mechanism. This transformation does not require any activating additives and is applicable to a broad variety of aldehydes.

A highly sustainable catalytic protocol for the coupling of alcohols and amines for selective monoalkylated amines using Ni(II)–NΛNΛO pincer type complexes through the borrowing hydrogen methodology is described. An array of Ni(II) catalysts (1–3) was synthesized and characterized by various spectral and analytical methods. Furthermore, the distorted square planar geometry of the complexes (1 and 2)

tungsten‐catalyzed N‐alkylation reaction of anilines with primary alcohols via BH/HA. This phosphine‐free W(phen)(CO)4 (phen=1,10‐phenthroline) system was demonstrated as a practical and easily accessible in‐situ catalysis for a broad range of amines and alcohols (up to 49 examples, including 16 previously undisclosed products). Notably, this tungsten system can tolerate numerous functional groups,
