Jadeja, Mitesh B. Gondaliya, Devang M. Mokariya, Manish Shah* Chemical Research Laboratory, Department of Chemistry Saurashtra University, Rajkot - 360005, India *E-mail address: drmkshah99@gmail.com ABSTRACT N,N,O-Tridentate ligands were prepared by the condensation of 1-(Benzothiazole 2-yl) hydrazine with substituted salicyldehydes or different aromatic ketones. New synthesized metal complex are thermally stable and neither air- nor moisture-sensitive. Suzuki–Miyaura cross-coupling reaction is carried out in present of various ligands and palladium salts, Different solvent/water ratio with different Base and studied effects its effect on the performance of the coupling reaction. Keywords: Palladium complex, N,N,O-Tridentate ligand, Schiff base, Suzuki-Miyaura cross-coupling reaction 1. INTRODUCTION In present studies the Suzuki reaction is carried out in aqueous phases including water and water/organic mixtures as solvents for the Suzuki reaction has also received significant attention, as water is, environmental friendly, economical, and allows simple separation and catalyst recycling.
