The U atom in the title complex, [U(C(17)H(15)N(3)O(2)S)O(2)(C(4)H(10)O)], exists within a distorted penta-gonal-bipyramidal geometry where the oxide O atoms occupy axial positions [O-U-O = 179.61 (18)°] and the penta-gonal plane is defined by the N(2)O(2) atoms of the tetra-dentate Schiff base ligand and the O atom of the butan-2-ol mol-ecule. In the crystal, centrosymmetric aggregates are for...

The gold-catalyzed [3+3]-cycloaddition reaction of propargyl esters and azomethine imines has been developed. The reaction provides a rapid entry into a wide range of substituted tetrahydropyridazine derivatives from simple starting materials. A stepwise mechanism involving addition of the 1,3-dipole to a gold-carbenoid intermediate is proposed.

The O-C(6)H(4)-CH=N-C(6)H(4)-O dianion of the title compound, [Mn(C(13)H(9)NO(2))(C(7)H(5)O(2))(C(2)H(6)OS)], acts as an O,N,O'-chelate to bind to the Mn(III) atom, and the three atoms constitute three points [O-Mn-O = 174.43 (11)°] of an octa-hedron around the metal atom. The azomethine linkage is disordered over two positions in a 0.657 (13):0.343 (13) ratio. The deprotonated salicyldehyde an...

This work is a proof-of-concept of the use azomethine-bearing diamines as novel hardeners standard epoxy compounds to yield cleavable and thermoformable covalent adaptable networks (CANs), with functional properties otherwise comparable conventional networks. A suitable aromatic diamine (TPA-o-PD) was synthesised at acceptable purity for intended successfully reacted DGEBA. The resulting cured ...

Linear and hyperbranched poly(azomethine)s (PAMs)-based on triphenylamine moieties are synthesized and used as the functioning layers in the Ta/PAM/Pt resistive switching memory devices. Comparably, the hyperbranched PAM with isotropic architecture and semi-crystalline nature shows enhanced memory behaviors with more uniform distribution of the HRS and LRS resistances.

Stereoselective synthesis of pyrazolidinones via dipolar cycloaddition of azomethine imines with active esters under Lewis base catalysis is presented. The active esters are readily generated in situ from the corresponding acids. Products, which are obtained with excellent diastereocontrol and high enantioselectivity, contain along with the pyrazolidinone core also the tetrahydroisoquinoline st...

A copper-catalyzed method for the regioselective 1,3-dipolar cycloaddition of azomethine imines to terminal alkynes has been developed. Through the use of a chiral phosphaferrocene-oxazoline ligand, a wide range of substrates can be coupled to generate useful heterocycles in very good enantiomeric excess.

In this study, we synthesized two novel carboxylic acid and carboxylate compounds, both of which had an amide group linked with an azomethine moiety to introduce photoinduced switching of the intramolecular NH...O hydrogen bond. We suggest that the cis-carboxylate compound forms a stronger intramolecular NH...O hydrogen bond than the cis-carboxylic acid compound.

Intramolecular transannular dipolar cycloaddition was investigated as a key step in a synthetic approach to the core of the sarain alkaloids; although the use of an azomethine ylide was unsuccessful with the chosen aldehyde substrate, cycloaddition with a nitrone did give the alternative regioisomeric bridged cycloadduct.
