“…Heck reactions are commonly carried out by using various homogeneous Pd salts as catalyst (palladium chloride, palladium acetate) or Pd complexes containing phosphine ligands. (Kantam et al, 2013;Marandi and Koukabi, 2021). However, most phosphine ligands are costly, toxic, air and moisture sensitive.…”

“…They are also used as natural products, molecular organic materials and components for optical device production [17,18]. Until now, soluble palladium(II) complexes with various ligands such as oxazolines, thioureas, pyridines, pyrazoles [19], imidazole [20], Schiff bases [21,22] and Nheterocyclic carbines [23] have been used as effective catalysts. Among these ligands, Schiff base ligands have superior properties such as ease of obtaining, low cost, thermal and chemical stability [24].…”

The work include the synthesis, spectroscopic characterization and as well as catalytic activities of Fe(II), Zn(II), Ru(II), and Pd(II) complexes with a novel Schiff base ligand derived from methyl 2amino-5,5,7,7-tetramethyl-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxylate and salicylaldehyde. Spectroscopic techniques including IR, UV-Vis, NMR, and mass analysis as well as elemental analysis and magnetic susceptibility measurement were used to identify the compounds. Based on elemental and spectral studies octahedral geometry was proposed to Fe(II), Zn(II) and Ru(II) complexes and square planar geometry was proposed to Pd(II) complex. To improve more efficient and stable catalysts, we wanted to study if there is any influence the catalytic activity of ruthenium complex for the transfer hydrogenation of ketones and we wanted to examine the catalytic activities of palladium complex in Suzuki C-C cross coupling reactions under various conditions.

A facile palladium(II)‐porphyrin catalytic system has been developed for the Mizoroki‐Heck coupling of aryl bromides with alkyl acrylates under mild conditions. Seven different porphyrins (H2TPP, H2TpCPP, H2TpAP, H2TpTP, H2TSTpSPP, H2TmHPP and H2TmCPP) and their complexes with palladium (Pd‐TPP, Pd‐TpCPP, Pd‐TpAP, Pd‐TpTP, Pd‐TSTpSPP, Pd‐TmHPP and Pd‐TmCPP) were synthesized, and examined their catalytic role in the synthesis of alkyl cinnamates in DMF. The complex, Pd‐TSTpSPP showed better activity in the present conversion. This finding has significant advantages like operational simplicity, easy synthesis of porphyrin ligands and their complexes with palladium, utilization of safer and recyclable catalyst and high yields of Mizoroki‐Heck products.
