Studies on Tertiary Amine Oxides. LIII. Studies on Preparation and Properties of 3, 2'-Diquinolyl N-Oxides

N-Oxidation of 3, 2'-diquinolyl (4) was examined under various conditions to give the 1-oxide (5) and 1, 1'-dioxide (6). The 1-oxide group in 5 and 6 was easily deoxygenated by heating with carbon disulfide in N, N-dimethylformamide (DMF); the 1'-oxide group resisted this deoxygenatio...

Zusammenfassung:N-Oxidation of 3, 2'-diquinolyl (4) was examined under various conditions to give the 1-oxide (5) and 1, 1'-dioxide (6). The 1-oxide group in 5 and 6 was easily deoxygenated by heating with carbon disulfide in N, N-dimethylformamide (DMF); the 1'-oxide group resisted this deoxygenation. This indicates that 1-oxide function has a slight nitrone-like property, and this was supported by the fact that nitation of 5 did not give γ- or α-nitro compound.
