Visible-light photoredox catalysis has been utilized in a new multicomponent reaction forming β-functionalized δ-diketones under mild conditions in an operationally convenient manner. Single-electron reduction of in situ generated carboxylic acid derivatives forms acyl radicals that react further via 1,2-acylalkylation of olefins in an intermolecular, three-components cascade reaction, giving v...

Martensitic transfromation in TiNi alloys of the near-equiatomic composition has been studied by utilizing electron microscopy and diffraction under various thermal treatments. It has been observed that the martensitic transformation is associated with the variants of the product. Two orientations of the martensitic phase were observed as adjacent regions in quenched alloys. These orientations ...

The title compound, C(16)H(17)N(3)O(3), exists in the E configuration with respect to the azomethine double bond. The mol-ecule is close to planar, with a dihedral angle of 6.7 (1)° between the aromatic rings. The phenolic O atom functions as donor and acceptor by forming intramolec-ular O-H⋯O and inter-molecular N-H⋯O hydrogen bonds, respectively. Two-dimensional packing is fashioned through a...

An efficient method towards the synthesis of quinoline fused tricyclic compounds involving an intramolecular 1,3-dipolar nitrile oxide cycloaddition reaction utilizing Baylis-Hillman derivatives in good yields has been described for the first time. A highly functionalized tricyclic framework was created by forming two rings and two adjacent stereocentres through the formation of two N-C bonds, ...

there are three different basic dykes in the northeast of golpayegan area, central part of sanandaj-sirjan zone (ssz) including: mylonitic gabbros (group 1), alkali dioritic-basanitic dykes (group 2) and alkali monzogabbroic to monzodioritic dykes (group 3). group 2 and 3 cut post-collisional rocks and are related to after subduction processes of neo-tethys. geochemistry characteristic of studi...

Abstract Thermoforming is a complex process with numerous parameters that potentially have an influence on the wall thickness distribution of end product. Test benches do not allow for measuring all relevant influences. Numerical simulations therefore proven to be useful tool in order obtain deeper insight into and mutual interactions between input parameters. Forming air impact thermoforming c...

administrative organizations for doing public services and keeping public order are obliged to make decision and do unilateral and bilateral actions. what are rules and conditions of forming unilateral administrative actions? regarding observing principle of rule of law on administration, administrative organizations should observe principles and rules for doing their duties and decision-making...

The title compound, [CoK(C(2)H(6)NO(3)S)(3)](n), is isotypic with its Ni(II) analogue. The Co(II) atom is chelated by the three taurinate ligands in a distorted octa-hedral geometry and in a facial manner. Each taurinate ligand bridges two K(+) ions via its sulfonate group, forming a three-dimensional framework. Weak N-H⋯O hydrogen bonding is observed in the crystal structure.
