Abstract

This article describes a series of synthetic chemistry experiments suitable for advanced undergraduate students, which will allow them to compare stoichiometric and catalytic methodologies. In the stoichiometric reactions, intermediate products in the reduction of nitrobenzene will be obtained. For the catalytic reactions it is illustrated that FeCl₂py₄⁺ acts as catalyst for the oxidation of aniline using HOOH or t-BuOOH as the oxidant. Several parameters will be modified in order to show their influence in the catalytic system.

  One principle of green chemistry is the elimination of waste in chemical processes prior to its generation. For this dry laboratory, a procedure for the nitrosation of 2,5-hexanedione is evaluated using a recently described metrics system. Since the ...
