Electrophilic Indoles/Pyrroles: The first synthesis of indole- and pyrrole-derived benziodoxole reagents in one step from the heterocycles is reported. The new indole- and pyrrole-BX reagents are stable up to 150 °C and can be used for selective heterocycle transfer onto the C−H bonds of arenes ortho to directing groups by using rhodium or ruthenium catalysts.
