9-methylenedioxybenzo[i]phenanthridine is one of the more potent benzo[i]phenanthridine derivatives in regard to topoisomerase I-targeting activity and cytotoxicity. The structure-activity relationship observed with these substituted dibenzo[c,h]cinnolines parallels that observed for benzo[i]phenanthridine derivatives. Compared to similarly substituted benzo[i]phenanthridines, the dibenzo[c,h]cinnoline analogues

Upon treatment of o- and p-(phenylseleno)nitrobenzenes with sodium methoxide quantitative exchange reactions took place, affording the corresponding methoxynitrobenzenes. Upon reaction between 2,4-bis(phenylseleno)nitrobenzene 2 and sodium methoxide, an unusual regiopure formation of 4-methoxy-2-(phenylseleno)nitrobenzene 3 was observed. This product remained unreactive toward an excess of sodium methoxide

A variety of deactivated arenes were nitrated to their corresponding nitro derivatives in excellent yields under high-speed ball milling condition using Fe(NO3)3·9H2O/P2O5 as nitrating reagent. A radical involved mechanism was proposed for this facial, eco-friendly, safe, and effective nitration reaction.
