چکیده
A new derivative of the ligand (2-aminoethyl)bis(2-pyridylmethyl)amine (uns-penp), capable for covalent immobilization on silica, was synthesized. Silica powder column chromatography and mesoporous monoliths served as surface material. Functionalized silica sufficiently characterized with reflectance UV/Vis FTIR techniques. Copper(I) successfully complexed immobilized exhibits reversible reactivity towards dioxygen at low temperatures. Suspending oxygen species toluene temperatures led to selective oxygenation benzaldehyde, determined by GC-MS. complexes ligands Me-PTS-uns-penp Me-Prop-uns-penp were prepared model reaction behavior in solution. Additionally, solid copper peroxido these obtained precipitation sterically demanding anion tetraphenylborate. Furthermore, could be a treating corresponding copper(I) dioxygen. With all oxygenated catalytic oxidation observed.

A novel tripodal ligand with three different arms, viz., pyridine, phenol and an oxime and its copper(II) complex were synthesised. The X-ray crystal structure of the compound reveals that it is a dinuclear complex consisting of two copper(II) ions doubly bridged by two oximato groups in a trans arrangement. The complex contains unusual cis-axially coordinated phenolates as well as a novel inte...

We describe a multidentate tripodal ligand in which three pendant arms carrying di(2-picolyl)amine units are linked to the ortho positions of a tris(o-xylyl) scaffold, providing N(CH(2)-o-C(6)H(4)CH(2)N(CH(2)py)(2))(3) (L). Reaction of L with CuCl(2) in the presence of hexafluorophosphate anion afforded blue cubes of [(CuCl)(3)L](PF(6))(3)·5H(2)O (1). Crystallographic studies of 1 revealed that...
