A water soluble Ni-Schiff base complex for homogeneous green catalytic C S cross-coupling reactions

Since the embarkation of C – S cross-coupling from aryl halides with thiols a handful of works have been contemplated in aqueous medium. Herein, we report an example of a water soluble Ni-Schiff base complex as the green catalyst for the synthesis of thioethers. We have synthesized a Ni-Schiff base complex [NiL(H2O)2 ](ClO4)2 using N 4 -donor Schiff base ligand (1,3-bis(((E)-pyridin-2-ylmethylene)amino)propan-2-ol) and characterized by single crystal X-ray diffraction (SC-XRD) study along with different spectral analyses. The complex is mono-nuclear and cationic in nature having two perchlorate anions. Two water molecules remain coordinated with the Ni(II)-centre. The hydrogen bonding interaction through coordinated water and perchlorate anions connect the monomeric units to form 2D supramolecular structure. Based on its aqueous solubility, the complex has been used for the catalytic C – S cross-coupling reaction between aryl iodide and aryl or alkyl thiols using TBAB at 60 ◦ C in aqueous media (yield 92%). At room temperature, an isolated yield of 57% can be achieved. This environmentally benign protocol is paramount in view of the environmental sustainability

Synthesis and Crystal and Molecular Structure of trans-[PtCl2(8-dqmp)2]* (8-dqmp = diethyl 8-quinolylmethylphosphonate)

The complex trans-PtCl2(8-dqmp)2 – trans-dichloro-bis(diethyl 8-quinolylmethylphosphonate-κN)platinum(II) – has been synthesized and the molecular structure has been determined by a rystallographic study. The platinum atom has a slightly distorted trans square-planar configuration with Pt1–N1 = 2.042(4) and Pt1–Cl1 = 2.306(1) Å. The dihedral angle between the Pt coordination plane and the mean plane of the 8-quinolylmethyl moiety is 65.1(1)°. The complex reveals a very interesting feature: a very short methylene proton–platinum distance of 2.309(5) Å occupying approximately axial positions around the central metal atom for the hydrogen atom H10B. Refinement was performed by least-squares methods to a final R value of 3.02%
