1. Role of Hydrogen Bonding in the Oxidation of Thianthrene 5-Oxide with Peroxy Acids

2. (b) According to these authors, the calculated potential energy difference between s-trans (μ = 3.11 D) and s-cis (μ = 1.43 D) performic is of 2.01 kcal/mol at the B3LYP/6-311++G(d,p) level in gas phase. Our B3LYP/6-311++G(3df,2pd) calculations led to the following results:  μs-cis= 1.36 D (gas), 1.45 D (benzene), 1.51 D (CH2Cl2) and μs-trans= 3.09 D (gas), 3.38 D (benzene), 3.67 D (CH2Cl2); (Gs-trans−Gs-cis)gas= 2.48 kcal/mol, (Gs-trans−Gs-cis)benzene= 1.77 kcal/mol, (Gs-trans−Gs-cis)CH2Cl2= 0.62 kcal/mol.

3. Role of solvent in the oxidation of some organic compounds by peroxyacids

4. The s-cis form of neutral peroxy acids has always been assumed as the only reactive conformer in all theoretical studies on epoxidation reactions of both alkenes and allylic alcohols.3-5

5. On the Origin of Substrate Directing Effects in the Epoxidation of Allyl Alcohols with Peroxyformic Acid
