Abstract
The new Co(II) - carboxamide complex (1) and Co3O4 nanoparticles (2), by way of thermal decomposition of (1) have been efficiently synthesised in the environment-friendly. X-ray diffraction reveals a slightly distorted octahedral coordination of cobalt (four nitrogens and two oxygens) in (1) and regular octahedral or tetrahedral ones (oxygens only) in (2). The investigation of (1) and (2) in the Mizoroki-Heck and epoxidation of alkens reactions showed them both to be powerful, green and inexpensive catalysts. © 2020 John Wiley & Sons, Ltd

Abstract
The complexes PdII(qcq)(OAc) and PtII(qcq)Cl have been synthesized using environmentally benign synthesized ligands and characterized by elemental analyses: Fourier transform infrared spectroscopy, UV–visible spectroscopy, 1H NMR spectroscopy, and X-ray diffraction. The catalytic activity of the complex was assessed, in different media, for the Mizoroki–Heck coupling reaction for typical aryl halides and terminal olefins under aerobic conditions. Since the base and the solvent were found to influence the efficiency of the reaction, reaction conditions, temperature, time, and the amount of K3PO4 and a mixture of H2O/PEG, were optimized. We found, for the Mizoroki–Heck reaction coupling less...

Abstract
A targeted new dioxo molybdenum(VI) ONO Schiff base complex was prepared for catalyzing epoxidation of olefins in water. This complex was characterized by FT-IR, NMR, UV–Vis, and X-ray crystallography techniques. DFT calculations are additionally performed to find ground and transition states for finding electronic structure and UV–Vis assignment. Afterward, a new protocol was defined for sustainable catalytic epoxidation of olefin in water using this complex as a green catalyst, and also remarkable results are obtained, such as turn over number up to 1400. © 2020 Elsevier B.V
