Zeolite enslaved transition metal complexes as novel heterogeneous catalysts for synthesis of polycyclic heterocycles using suzuki--miyaura cross coupling reaction under greener conditions

Abstract In the present work we report the construction of zeolite enslaved transition metal complexes (Pd2+, Ni2+) as novel heterogenous catalysts for synthesis of polycyclic heterocycles using suzuki—miyaura cross coupling reaction in ethanolic medium. The synthesized catalysts were characterized by employing UV-Vis, FT-IR, magnetic susceptibility, N2 sorption, XRD, XPS, FE-SEM analysis. Results of the study advocate that newly developed catalysts give rise to a rapid and easy synthesis of various polycyclic heterocycles by Suzuki coupling reactions in impressive yields. In conclusion, developed catalyst may be used as versatile tool in the synthesis of various industrially and pharmaceutically important polycyclic heterocycles under greener conditions.
