1. Conformational analysis and electronic interaction study of some ortho-substituted alpha-ethylsulfonylacetophenones; and the oxidative rearrangement study of some ortho-substituted alpha-ethylthioacetophenones / Análise conformacional e estudo das interações eletrônicas em alfa-etilsulfonilacetofenonas-orto-substituídas e o estudo do rearranjo oxidativo de alfa-etiltioacetofenonas-orto-substituídas
The first part of this thesis reports the conformational study of some -ortho-substituted α-ethylsulfonylacetophenones o-X-PhC(O)CH2SO2Et (X= OMe 1, Me 2, F 3, Cl 4, Br 5 e NO2 6) through the analysis of the carbonyl stretching IR band in solvents of increasing polarity supported by HF/6-31G** ab initio computations. The good match between IR frequencie
