ChemPlusChem, Volume 87, Issue 12, December 2022., 2022 2‐Hydroxy‐1‐naphthaldehyde oxime was oxidized by a D−A type self cycloaddition to spiro compound. Free reaction energy is calculated at −82.0 kcal/mol indicating its predominance over the intramolecular cyclization of −37.6 kcal/mol. 8‐methoxy substituted oxime is sterically guided to 9‐methoxynaphtho[1,2‐d] instead of spiro adduct resulting to the ...

Propellants, Explosives, Pyrotechnics, Volume 47, Issue 12, December 2022., 2022 Abstract To establish a database of performance values in the small‐scale shock reactivity test (SSRT), common secondary explosives based on organic nitrates (e. g. PETN) and nitramines (e. g. RDX and HMX) as well as aromatic (e. g. TNT), heteroaromatic (e. g. TKX‐50 and MAD−X1) and open chain systems (e. g. FOX‐7) were investigated.

A survey of liquid crystalline oxadiazoles [PDF]
ChemInform, Published Online: 21 Jul 2008, 2008 We propose a survey of those oxadiazole compounds, which are mesogenic. We will see that they can have bend-shaped molecules, a biaxial nematic phase, or other interesting peculiarities in the nematic and smectic phase. With large electric dipoles and luminescent properties, these materials are also very appealing for technological applications.

1,3,4-Oxadiazole N-Mannich Bases: Synthesis, Antimicrobial, and Anti-Proliferative Activities
Molecules, 2021 The reaction of 5-(3,4-dimethoxyphenyl)-1,3,4-oxadiazole-2(3H)-thione 3 with formaldehyde solution and primary aromatic amines or 1-substituted piperazines, in ethanol at room temperature yielded the corresponding N-Mannich bases 3-arylaminomethyl-5-(3,4-

Fan-shaped and toric textures of mesomorphic oxadiazoles [PDF]
Phase Transitions, Vol.80, 987-998, 2007, 2007 When a family of non symmetrical heterocycled compounds is investigated, a variety of mesophases can be observed with rather different features. Here we report the behaviour of seven different members among a family of such materials, that consists of mesomorphic oxadiazole compounds.

Growth of toric domains in the smectic phase of oxadiazoles [PDF]
Phase Transitions, Volume 81, Issue 5 May 2008, pages 471 - 477, 2007 In a previous paper (Phase Transitions, 80(9), 987, 2007) we discussed the smectic and nematic textures of some mesomorphic oxadiazole compounds with terminal Cl-substituent. Optical microscope investigations showed a very interesting behaviour of smectic and nematic phases; the smectic phase has fan-shaped and toric textures and the nematic phase has ...

Therapeutic potential of oxadiazole or furadiazole containing compounds
BMC Chemistry, 2020 As we know that, Oxadiazole or furadi azole ring containing derivatives are an important class of heterocyclic compounds. A heterocyclic five-membered ring that possesses two carbons, one oxygen atom, two nitrogen atoms, and two double bonds is known as ...

Photophysical characterizations of 2-(4-Biphenylyl)-5 phenyl-1,3,4- oxadiazole in restricted geometry [PDF]
, 2008 Langmuir and Langmuir-Blodgett (LB) films of nonamphiphilic 2-(4-Biphenylyl)-5 phenyl-1,3,4- oxadiazole (abbreviated as PBD) mixed with stearic acid (SA) as well as also with the inert polymer matrix poly(methyl methacrylate) (PMMA) have been studied.
