✦ Synopsis

Chemistry in Superacids. Part 35. NO 2 Cl-3MXn Systems: Superelectrophilic Aprotic Nitrating Agents for Deactivated Aromatics.

-The superelectrophilic nitrating agent NO 2 Cl-SbCl 5 (AlCl 3 ) represents a useful tool for the nitration of deactivated aromatics affording the corresponding substituted nitroarenes in good yield and with moderate m-selectivity. In several cases, a chlorination side reaction is observed as demonstrated for pentachlorobenzene (V). -(OLAH, G. A.

3 ) 3 . The reaction proceeds with high regioselectivity. Thus, methanesulfonylation of 1,2,4-trifluorobenzene (V) exclusively affords the 1-mesyl-2,4,5-trifluorobenzene (VI). In dihalobenzenes [cf. compounds (VII) and (Ia)], the para-position is predominantly substituted [cf. compound (VIII)]. Othe
