crystal of a new copper(II) Schiffbasecomplex [Cu(HL)(H2O)NO3] (1) (H2L = 2-[(2-hydroxy-1,1-dimethyl-ethylimino)methyl]phenol}) and its nanostructure have been synthesized by slow evaporation of a methanol solution and sonochemical process, respectively. The structure of complex 1 was determined by FTIR, UV–Visible spectra and single-crystal X-ray diffraction. Nanostructure of the complex was characterized

Economical Oxygenation of Olefins and Sulfides Catalyzed by New Molybdenum(VI) Tridentate Schiff Base Complexes: Synthesis and Crystal Structure
cis-dioxomolybdenum(VI) complexes (MoO2YxCH3OH) were synthesized using MoO2(acac)2 and 2[(1-hydroxy-2-methylpropane-2-ylimino)methyl]phenol derivatives as tridentate ONO donor Schiff base ligands (H2Yx). MoY1 was crystallized in orthorhombic space group Pbca. The epoxidation of olefins using tert-butyl hydroperoxide and oxidation of sulfides to the sulfoxides by hydrogenperoxide were efficiently enhanced
five- and six-coordinated complexes of ZnII with OH-rich molecules possessing an ONO binding core were synthesized, characterized and their structures were established by single-crystal X-ray diffraction. The corresponding metal ion geometries were found to be distorted tetrahedral, square pyramidal and octahedral, respectively. The complexes exhibit interesting lattice structures such as layered and corrugated

A process for the preparation of amino alcohols includes condensing a compound of Formula (II), a stereoisomer, a tautomer, or a salt thereof with a compound of Formula (IlIa) or Formula (Illb), a stereoisomer, a tautomer, or a salt thereof to form a condensation product; hydroxylating or acyloxylating the condensation product in the presence of an oxidant to obtain a hydroxylation or acyloxylation product; and subjecting the hydroxylation or acyloxylation product to one or more subsequent reactions comprising a hydrolysis reaction, alcohol deprotection, an amino lysis reaction, or a combination of two or more thereof to obtain an amino alcohol of Formula (I).
