Abstract
The isoquinolone scaffold can be arylated using aryliodonium salts as the coupling partners at either the C4 or C8 position. The C4-selective arylation was successfully achieved via an electrophilic palladation pathway, whereas an Ir(III) catalytic system resulted in C-C bond formation exclusively at the C8 position.
