Synthesis and characterization of oxo-vanadium complex anchored onto SBA-15 as a green, novel and reusable nanocatalyst for the oxidation of sulfides and oxidative coupling of thiols
Abstract The present work describes the synthesis of a new oxo-vanadium complex immobilized on SBA-15 nanostructure as an efficient catalyst for oxidation of sulfides and oxidative coupling of thiols. Characterization of the resultant AMPD@SBA-15 nanostructure was performed by various physico-chemical techniques such as Fourier transform infrared spectroscopy, transmission and scanning electron microscopies
Immobilization of a nickel complex onto functionalized Fe3O4 nanoparticles: a green and recyclable catalyst for synthesis of 5-substituted 1H-tetrazoles and oxidation reactions
gravimetric analysis and vibrating sample magnetometer measurements. The catalytic behavior of the prepared nanohybrid as an efficient catalyst was successfully probed in the oxidation of sulfides, oxidative coupling of thiols and synthesis of 5-substituted1H-tetrazoles. This method was found to have significant advantages, including high yield, green reaction conditions, short reaction time, easy separation

N,N-bis(Trimethylsilyl)alkenesulfenamides 3, prepared by the reaction of trans-alkenesulfenates with TMSCI and LiHMDS, are modified to their corresponding S-alkenylthiophthalimides 6 which are then converted to alkenesulfenamides 7 bearing more general nitrogen functionality.

Eight stable N,N-bis(trimethylsilyl)-1-alkenesulfenamides (3) were synthesized by the reaction of 1-alkenesulfenate anions with TMSCl and LiHMDS. Compounds 3 were isolated either by distillation or by chromatography. 1-Alkenesulfenamides (3) can be desilylated in the presence of aldehydes and ketones that do not bear α-hydrogens, to afford 1-alkenesulfenimines (7) either as single isomers or as mixtures
