Metal-free regioselective nitration of quinoxalin-2(1H)-ones with tert-butyl nitrite

A metal-free coupling of quinoxalin-2(1H)-ones with tert-butyl nitrite has been developed. Distinctly from the previous functionalization of quinoxalin-2(1H)-ones, this nitration reaction took place selectively at the C7 or C5 position...

Microwave-Induced Surface-Mediated Highly Efficient Regioselective Nitration of Aromatic Compounds: Effects of Penetration Depth

Surface mediated highly regioselective nitration of aromatic compounds under diverse microwaveinduced conditions was investigated in this work. The effects of the penetration depth of the surfaces were found to be more crucial than other dielectric parameters. Despite significant progress of microwave-induced reactions, no reports have examined the penetration depth of the surfaces used in these processes.

Regioselective nitration of anilines with Fe(NO3)3·9H2O as a promoter and a nitro source

A novel and efficient ortho-nitration reaction of aniline derivatives using the inexpensive and nontoxic Fe(NO3)3·9H2O as a promoter and a nitro source has been developed.
