Selection of elastomeric membranes for the removal of volatile organics from water [PDF]

open access: yes, 1993
A wide range of homogeneous elastomeric membranes has been prepared using dicumylperoxide as a general cross-linking agent. The membranes have been used for both equilibrium sorption measurements and steady-state pervaporation experiments to study ...

Orthogonal, metal-free surface modification by strain-promoted azide–alkyne and nitrile oxide–alkene/alkyne cycloadditions [PDF]

open access: yes, 2012
In this article we present a fast and efficient methodology for biochemical surface patterning under extremely mild conditions. Micropatterned azide/benzaldoxime-surfaces were prepared by microcontact printing of a heterobifunctional cyclooctyne oxime ...

Synthesis, DFT Study and Antibacterial Activity of some Isoxazoline Derivatives Containing 1,4-benzothiazin-3-one Nucleus Obtained Using 1,3-dipolar Cycloaddition Reaction [PDF]

open access: yesIranian Journal of Chemistry & Chemical Engineering, 2020
Novel series of isoxazoline derivatives containing 1,4-benzothiazin-3-one ring (6a-h) were synthesized via 1,3-dipolar cycloaddition reactions of arylnitrile oxides 5a-d on 4-allyl-2-(substituted)-1,4-benzothiazin-3-ones 3 and 4 led to polyheterocyclic ...

1,3-Dipolar cycloadditions of 2-thio-3-chloroacrylamides with nitrile oxides and nitrones [PDF]

open access: yes, 2010
1,3-Dipolar cycloadditions of 2-thio-3-chloroacrylamides with nitrile oxides and nitrones is described. A series of novel isoxazolines are isolated from the nitrile oxide cycloadditions, whilst the isoxazolines generated from the nitrone cycloadditions ...

Inverse electron-demand 1,3-dipolar cycloaddition of nitrile oxide with common nitriles leading to 3-functionalized 1,2,4-oxadiazoles [PDF]

open access: yes, 2011
A carbamoyl-substituted nitrile oxide was generated upon treatment of easily available 2-methyl-4-nitro-3-isoxazolin-5(2H)-one with THF (not dried); the reaction proceeded efficiently even in the absence of any special reagents and reaction conditions ...

The Participation of 3,3,3-Trichloro-1-nitroprop-1-ene in the [3 + 2] Cycloaddition Reaction with Selected Nitrile N-Oxides in the Light of the Experimental and MEDT Quantum Chemical Study

open access: yesMolecules, 2021
The regioselective zw-type [3 + 2] cycloaddition (32CA) reactions of a series of aryl-substituted nitrile N-oxides (NOs) with trichloronitropropene (TNP) have been both experimentally and theoretically studied within the Molecular Electron Density Theory

An anomalous hydration/dehydration sequence for the mild generation of a nitrile oxide [PDF]

open access: yes, 2011
A nitrile oxide containing a carbamoyl group is readily generated upon the treatment of 2-methyl-4-nitro-3-isoxazolin-5(2H)-one with water under mild reaction conditions, even in the absence of special reagents.
