3-Acetylindole reacts regioselectively with NO2BF4 in the presence of SnCl4 to produce 3-acetyl-5-nitroindole or 3-acetyl-6-nitroindole, depending on the temperature, both in excellent yields.

We have developed a metal-free, mild, and green synthetic route toward benzothieno[3,2-b]benzofurans by the annulation of 3-nitrobenzothiophene with phenols. The reaction was found to be general with a range of substituted phenols. In addition, we could extend the methodology for the synthesis of pentacenes and could demonstrate the synthesis in gram-scale. Moreover, we extended the strategy for the synthesis of benzothieno[2,3-b]benzofurans by starting from 2-nitrobenzothiophenes.

A mild and efficient method for the mononitration of aromatic and olefinic compounds is described. This method is especially useful for active substrates.
