Agro-Waste Generated Pd/CAP-Ash Catalyzed Ligand-Free Approach for Suzuki–Miyaura Coupling Reaction

Aqueous extract of CAP-ash: An innovative approach for Suzuki-Miyaura coupling reaction in palladium catalyzed ligand-free condition

“…In continuation of our research program [20][21][22][23][24][25][26], herewith, we present a highly green protocol for SMcoupling reaction using ethanol together with an aqueous extract of CAP-ash (AECAP) and Pd(OAc) 2 for C-C bond formation reaction (Scheme 1). Traditionally, it can be an appropriate alternative for moderate base and solvent.…”

Revisit to Henry reaction by non conventional heterogeneous and efficient catalyst for nitroalcohol synthesis

“…In continuation of our research work concerning the development of natural catalysts for organic transformations [23][24][25][26][27][28][29][30][31][32], herein, we report an efficient synthesis of 2-nitro alcohols catalysed by CES-catalyst as natural base catalyst at ambient temperature using the environmentally benign EtOH: water (1:1) solvent system. CEScatalyst obtained from chicken eggshells contains calcium carbonate 85-95% along with 1.4% magnesium carbonate, 0.76% calcium phosphate, 4% organic matter and trace amount of Na, K, Zn, Mn, Fe and Cu [33].…”
