Catalytic N-radical cascade reaction of hydrazones by oxidative deprotonation electron transfer and TEMPO mediation

Compared with the popularity of various C-centred radicals, the N-centred radicals remain largely unexplored in catalytic radical cascade reactions because of a lack of convenient methods for their generation. Known methods for their generation typically require the use of N-functionalized precursors or various toxic, potentially explosive or unstable radical initiators. Recently, visible-light...

Synthesis of mesoporous TiO2-SiO2-Ag and investigation of its structural and photocatalytic properties under visible light and ultra-violate

In this project, mesoporous titanium oxide-silicon oxide doped by silver (TiO2-SiO2-Ag) was hydrothermally synthesized. Titanium isopropoxide, tetraethyl orthosilicate and silver nitrate were used as precursors for TiO2, SiO2 and Ag, respectively. Initially TiO2-SiO2 mesoporous nanocomposite was synthesized with weight ratios of silica to titania SiO2:TiO2:3:1 via hydrothermal method at 70˚C an...
