Abstract:
In this work, the synthesis of an N-monoarylated dihydrophenazine is reported together with its interconversion to its oxidized mono-cationic form. While the reduced state was employed for the dechlorination of aromatic substrates, the oxidized mono-cationic one was exploited for the formation of C-N bonds between aryl rings and azoles, which was achieved with high yields and very low catalyst loadings (down to 0.5 mol%).

o-hydroxy phenols are oxidized to o-quinones and p-hydroxy phenols to p-quinones. Such redox reactions involve the transfer of two electrons and two protons. The reversible redox...

Reduction of Alkenes: Asymmetric Catalytic Hydrogenation
The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...

Reduction of Alkynes to cis-Alkenes: Catalytic Hydrogenation
Like alkenes, alkynes can be reduced to alkanes in the presence of transition metal catalysts such as Pt, Pd, or Ni. The reaction involves two sequential syn additions of hydrogen via a cis-alkene intermediate.
