Epoxy‐functionalized porous organic polymers via diels‐alder cycloaddition reaction for atmospheric water capture

Byun, Yearin ; Coskun, Ali

In: Angewandte Chemie, 2018, p. -

We report on the synthesis of highly microporous, epoxy-functionalized porous organic polymers (ep-POPs) through one pot, catalyst-free Diels-Alder cycloaddition polymerization. The high oxygen content of ep-POPs offered efficient hydrogen bonding sites for water molecules, thus leading to high water uptake capacities, up to 39.2-42.4%, under a wide temperature range of 5-45oC, covering the...

Application of photoclick chemistry for the synthesis of pyrazoles via 1,3‐dipolar cycloaddition between alkynes and nitrilimines generated in situ

Remy, Richard ; Bochet, Christian G.

In: European Journal of Organic Chemistry, 2018, vol. 2018, no. 3, p. 316–328

The photochemical extrusion of gaseous nitrogen from 2,5-disubstituted tetrazoles to generate reactive nitrilimines in situ represents an efficient and attractive way to form dipoles that can be used to provide useful chemicals via 1,3-dipolar cycloadditions. The concept of “photoclick chemistry” already inspired numerous researchers, who exploited photochemical processes involving...
