Síntese dos N-Substituídos monoiminodióxidos de enxofre em microondas

Abstract

With a view to introducing the use of microwave heating in synthesis In the Chemistry Department of UEM, bibliographic research was carried out on microwaves in organic synthesis, the following were highlighted in this context microwave topics. For microwave synthesis, in this work the method of choice was chosen. obtaining N-Substituted sulfur monoiminodioxides, R-NSO (where R = Ph; ArSO 2), as an extremely important intermediate substance in synthesis organic. Bibliographic research was also carried out on the synthesis and properties chemicals of the N-Substituted sulfur monoiminodioxides in which it was synthesized N-Sulfinylaniline whose structure has been confirmed with IR spectrum and mass spectra. The structures corresponding to the synthesis of N-Arylsulfinylmonoiminodioxides of sulfur (ArSO 2 NSO), showed a high reactivity compared to N-Sulfinylaniline, which caused hydrolysis of the compounds obtained until the formation of Corresponding arenesulfonamides. Microwave heating is an attractive way to conduct organic reactions for the great reduction of reaction time and good yields. The use of microwave heating in reactions without solvent has been pointed out as a Green Chemistry technique.
