Carbothioamide as Highly Efficient Ligand for Copper‐catalyzed Room Temperature Chan–Lam Cross‐Coupling Reaction

“…Although, catalytic potentiality of transition metal complexes of thiosemicarbazones have been reported for few reactions, the role of these ligands in catalysis however, is still a relatively new area of research . We are intrigued by this possibility and also to continue our research interest in exploring various catalytic methodologies in homogeneous systems herein, we wish to report the use of three different carbothioamide/thiosemicarbazide‐derived ligands L1 [2‐(4‐methoxybenzylidene)‐ N ‐phenylhydrazinecarbothioamide], L2 [2,2′‐(1,2‐diphenylethane‐1,2‐diylidene)bis(hydrazinecarbothioamide)] and L3 [2‐(4‐methoxybenzylidene)hydrazinecarbothioamide], (Figure .) in the C–N bond formation reaction .…”

Chemoselective Transfer Hydrogenation of Flavoring Unsaturated Carbonyl Compounds over Zr and Hf‐based Metal–Organic Frameworks

“…9 Vanillin is the most widely used flavor compound in the world and lignin, a major component of lignocellulosic biomass, could be utilized for the production of vanillin. 10 Homogeneous Ru-phosphine-diamine catalyst 11 and Rh (I) complexes 12 showed excellent performance for chemoselective reduction of these carbonyl compounds using molecular H 2 . However, the requirement for an extrabase for its activation, difficulties in recovery, and loss in catalytic activity in recycling convinced many researchers to use heterogeneous catalysts.…”
