Photomechanical response of sulfonylhydrazone molecular crystals

Sulfonylhydrazones are a novel hydrazone-based organic molecular photoswitch. The four derivatives with unsubstituted ando-,m- andp-nitro substituted sulfonylhydrazone (SH-1,SH-2,SH-3, andSH-4, respectively) derived fromp-toluenesulfonyl hydrazide and corresponding benzaldehydes were examined with respect to their solution state photoswitching and photomechanical response in the crystalline state. All the compounds displayed UV-inducedE→Zisomerization in the solution state, whereas the back conversion was slow. Single crystals ofSH-3displayed rapid and large photomechanical bending, whereasSH-1andSH-4crystals underwent slow bending to a comparatively lesser extent. On the contrary,SH-2crystals did not show any photomechanical effects. The photomechanical deflection of the crystal tip ofSH-1increased linearly; forSH-3, the deflection increased in a sub-linear manner for few seconds, after which it started to revert towards the light source. ForSH-4crystals, the photo-induced tip deflection initially increased in a sub-linear fashion, after which no motion was observed even after continuous exposure to UV light irradiation. The photomechanical behavior of the crystals was also inspected with the aid of velocity-time and acceleration-time plots that unravelled the instantaneous photomechanical motion at various time intervals.

Iron(III) phthalocyanine-chloride-catalyzed synthesis of sulfones from sulfonylhydrazones

In this study, sulfones are synthesized from sulfonylhydrazones catalyzed by iron(III) phthalocyanine chloride. This reaction offers broad substrate scope, occurs under mild conditions, utilized readily available reactants, and forms products in good-to-h

A complementary approach to 3,5-substituted pyrazoles with tosylhydrazones and terminal alkynes mediated by TfOH

A complementary method for the preparation of 3,5-substituted pyrazoles in moderate to high yields has been explored via TfOH-induced addition of tosylhydrazones to the terminal alkynes. This acid-induced addition procedure might be an operationally safe alternative compared to typical 1,3-dipolar cycloaddition as there is no involvement of diazo compounds.
