Scheme 6. Br/I-containing substrates and orthogonal experiment with Suzuki cross-coupling reaction. All reactions were performed on a 0.1 mmol scale, and yields were determined by isolation unless otherwise noted. a 0.5 mL THF was used as solvent instead. b 1H-NMR yield using mesitylene as an internal standard. Slightly lower isolated yield (shown in parentheses) is due to its low boiling point.
