Zr and Hf-metal-organic frameworks: Efficient and recyclable heterogeneous catalysts for the synthesis of 2-arylbenzoxazole via ring open pathway acylation reaction

Zirconium- and hafnium-based metal-organic frameworks which constructed by 12-coordinated clusters and 6-coodinated clusters were shown to be highly effective heterogeneous catalysts for the ring opening acylation of benzoxazole to 2-arylbenzoxazole under solvent free conditions. Owning the wide opening spaces structures and inherent formate sites, MOFs based on 6-connected Zr-6/Hf-6 node were able to identify a significantly enhanced yield in Bronsted acid catalyzed reactions under conventional heating and microwave irradiation. In addition, the detailed mechanism of active sites of the ring opening acylation reaction was confirmed by employing of density functional theory (DFT) calculations. (C) 2019 Elsevier Inc.

Aluminium(III) derivatives of N and O chelating ligands: Preparation, spectral [IR (H-1, C-13 and Al-27) NMR] and mass studies

Reaction of Al(OPri)(3) with 2-(o-hydroxy phenyl)-benzimidazole (pbmzH) and 2-(o-hydroxy phenyl)-benzothiazole (pbtzH) in different molar ratio in benzene solution afforded complex of the types [(mu-OPri)Al-2(pbmz)(2)(OPri)(2)] 1, [Al(OPri)(pbmz)(2)] 2, [Al(pbmz)(3)] 3, [(mu-OPri)Al-2(pbtz)(2)(OPri)(2)] 4, [Al(OPri)(pbtz)(2)] 5 and [Al(pbtz)(3)] 6. All these white to creamy white solid complexes are soluble in common organic solvents (such as C6H6, CCl4, n-hexane, DMSO, DMF etc.) and were characterized by elemental (C, H, N and AI) analysis as well as spectral [IR (H-1, C-13 and Al-27) NMR] and mass studies. On the basis of these spectroscopic data a plausible structure tentatively has been proposed for these complexes.

Three cuprous coordination polymers based on bisbenzoxazole: Syntheses, structures, luminescence and electrochemical properties

Three cuprous coordination polymers, namely: {[Cu(BBO)(3)]center dot PF6}n (1), {[Cu(BBO)(2)(CH3CN)(2)]center dot BF4}(n) (2) and {[Cu(BBO)(2)(SPPh3)]center dot BF4}n (3), bearing a bisbenzoxazole ligand, 2,2′-(1,4-butanediyl)bis-1,3-benzoxazole (BBO), have been synthesized, and structurally characterized by elemental analyses, IR, UV-Vis and single-crystal X-ray diffraction. The structural analysis revealed that the structures of coordination polymers I and 3 are both three-coordinated and show distorted trigonal planar geometry, but 2 is four-coordinated and a slightly distorted tetrahedron environment. In coordination polymer 1, adjacent copper(I) ions were bridged by three independent BBO to form a two-dimensional planar layer framework in which PF6- anion is filled in the hole. Two BBO link Cu(I) ions into a one-dimensional zigzag chain in coordination polymer 2, while acetonitrile as an ancillary ligand distributed on both sides of the one-dimensional chain. Coordination polymer 3 exhibits a single-stranded helix chain structure by two BBO bridging adjacent copper(I) ions. Luminescence properties investigation show that 1 have two emission peaks, which attributed to pi-pi* and n-pi* transitions. However 2 and 3 only had one emission peak, which may be attributed to [MLCT(d(10)(Cu) -> pi*]. This may be due to the synergy of the auxiliary ligands in coordination polymers 2 and 3. The cyclic voltammogram of 1-3 represent quasi-reversible Cue(2+)/Cu+ pairs. (C) 2019 Elsevier Ltd. All rights reserved.

A biradical oxo-molybdenum complex containing semiquinone and o-aminophenol benzoxazole-based ligands

We report a new mononuclear molybdenum(iv) complex, (MoOLLSQ)-L-BIS, in which L-SQ (2,4-di-tert-butyl o-semibenzoquinone ligand) has been prepared from the reaction of the o-iminosemibenzoquinone form of a tridentate non-innocent benzoxazole ligand, L-BIS, and MoO2(acac)(2). The complex was characterized by X-ray crystallography, elemental analysis, IR and UV-vis spectroscopy and magnetic susceptibility measurements. The crystal structure of (MoOLLSQ)-L-BIS revealed a distorted octahedral geometry around the metal centre, surrounded by one O and two N atoms of L-BIS and two O atoms of L-SQ. The effective magnetic moment (mu(eff)) of (MoOLLSQ)-L-BIS decreased from 2.36 to 0.2 mu(B) in the temperature range of 290 to 2 K, indicating a singlet ground state caused by antiferromagnetic coupling between the metal and ligand centred unpaired electrons. Also, the latter led to the EPR silence of the complex. Cyclic voltammetry (CV) studies indicate both ligand and metal-centered redox processes. (MoOLLSQ)-L-BIS was applied as a catalyst for the oxidative cleavage of cyclohexene to adipic acid and selective oxidation of sulfides to sulfones with aqueous hydrogen peroxide.
