A rhodium(III)-catalyzed sulfonamide directed ortho C–H carbenoid functionalization has been developed with good yields. This method is attractive due to its broad substrate scope, and enables derivation of diverse biologically active sulfonamide structures and late-stage modification of sulfa drugs.
This invention provides certain benzenesulfonamide derivatives and methods for using them in the treatment of susceptible neoplasms in mammals. Also provided are certain novel pharmaceutical formulations employing these benzenesulfonamide derivatives in combination with a carrier, and processes for preparing the benzenesulfonamide derivatives.

wherein:
R¹ is -NO₂,
or -NRaRb, where Ra and Rb are independently selected from the group consisting of hydrogen and C₁-C₆ alkyl; and
R² and R³ are independently selected from the group consisting of hydrogen, halo, C₁-C₆ alkyl, and trifluoromethyl, provided that no more than one of R² and R³ can be hydrogen;
with the proviso that if R¹ is -NO₂ or -NH₂, neither R² nor R³ can be hydrogen;
or a pharmaceutically acceptable salt or solvate thereof.
