The characterization of synthesized Schiff base ligands (L 1–L 5);(where L 1= N-salicyliden-
2, 3-diamino-cis-2-butenedinitrile, L 2= 3-methoxy-N-salicyliden-2, 3-diamino-cis-2-
butenedinitrile, L 3= 5-bromo-N-salicyliden-2, 3-diamino-cis-2-butenedinitrile, L 4= 5-nitro-N-
salicyliden-2, 3-diamino-cis-2-butenedinitrile, and L 5= 5-methoxy-N-salicyliden-2, 3-
diamino-cis-2-butenedinitrile) and their palladium complexes [PdL (PPh 3)](L 1–L 5) were
carried out by FT-IR, UV–vis, 1 H NMR, 13 C NMR and elemental analysis. The coordination
geometry of [PdL 3 (PPh 3)] was determined by single crystal X-ray crystallography. In this
structure the palladium center was in a partially distorted NNOP square planar coordination
environment. The catalytic potential of the synthesized complexes was evaluated in Suzuki–
Miyaura cross-coupling reaction by choosing different arylhalides and phenylboronic acid …
