Poly(1,3,4-oxadiazoles) via aromatic nucleophilic displacement [PDF]
, 1992 Poly(1,3,4-oxadiazoles) (POX) are prepared by the aromatic nucleophilic displacement reaction of di(hydroxyphenyl) 1,3,4-oxadiazole monomers with activated aromatic dihalides or activated aromatic dinitro compounds. The polymerizations are carried out in

Insight into wastewater decontamination using polymeric adsorbents [PDF]
, 2018 The use of polymeric adsorbent for decontamination of various sources of water was critically reviewed. This arises from the alarming increase in water scarcity in many parts of the world due to increase in population,which exerts immense pressure on ...

European Journal of Organic Chemistry, EarlyView.A manifold of catalytic reaction paths can operate in the Au(I)‐catalyzed heteroannulation of salicylic amides and alkynes. However, a subtle initial nucleophilic advantage of N versus O and a kinetic bottleneck at an advanced stage of the mechanistic machinery seems to suffice for the reaction to run on a single path and with exquisite selectivity. We

Push–Pull Ynamines and Push–Pull Ynamides: Synthesis, Structure, Reactivity, and Application
European Journal of Organic Chemistry, EarlyView.Push–pull ynamines and push–pull ynamides, which carry an EWG and an amino or amido group as EDG, are highly interesting classes of EDG‐EWG alkynes that have been intensively studied due to their exceptional reactivity. In this review, the synthesis, structure, reactivity, and application of push–pull ynamines, push–pull ynecarbamates, push–pull ...
