Asymmetric one-pot synthesis of cyclopropanes
Macedonian Journal of Chemistry and Chemical Engineering, 2016 Cycloaddition of the diazoalkanes to electron-deficient olefins (in situ) affords polysubstituted cyclopropanes in high yields (up to 85%). Deprotection of the ketal protecting group provided water-soluble cyclopropane-bearing carbohydrate in good yields.

Light Switchable Ionic Conductivity of Arylazopyrazole Modified Polysiloxanes
Advanced Materials Technologies, EarlyView.We present a polysiloxane functionalized with a novel arylazopyrazole dye that undergoes reversible photoisomerization. Upon lithium bis(trifluoromethanesulfonyl)imide addition and UV irradiation, the polymer exhibits a shift in tan(d) toward higher frequencies and enhanced ionic conductivity.
