- Synthesis of α-diketones from alkylaryl- and diarylalkynes using mercuric salts
-
Both alkylarylalkynes and diarylalkynes 1 are converted into the α-diketones 2 in good yield by the use of mercuric salts, e.g., mercuric nitrate hydrate or mercuric triflate, in the presence of water. Other mercuric salts, e.g., sulfate, chloride, acetate, or trifluoroacetate, do not provide the diketone product. A possible mechanism is proposed.

- Heterocycle-heterocycle strategies: (2-nitrophenyl)isoxazole precursors to 4-aminoquinolines, 1 H-indoles, and quinolin-4(1 H)-ones
-
Reductive heterocycle-heterocycle (heterocycle → heterocycle; H-H) transformations that give 4-aminoquinolines, 3-acylindoles, and quinolin-4(1H)-ones from 2-nitrophenyl substituted isoxazoles are reported. When this methodology is applied to 3,5-, 4,5-,

- Photoreactions of 1,2-bis-(2-nitrophenyl)ethane
-
The photolysis of 1,2-bis(2-nitrophenyl)ethane 1 is predominated by intermolecular redox process of the nitro group to afford 2-nitrobenzoic acid 4, 2-nitrobenzyl 2'-nitrophenyl ketone 5, 2,2'-dinitrobenzil 6 and dibenzo[c,g][1,2]diazocin-5,6-dione-N,N'-dioxide 7. In contrast, the lower homologue bis (2-nitrophenyl)methane is reported to undergo mainly intramolecular photoprocesses.
