We have discovered that phenyl tosylates can be used to arylate pyridines at the C3-position using a Pd(OAc)2–1,10-phenanthroline catalyst system. We also discovered that the reaction of 4-methylpyridine with naphthyl tosylates occurred on the methyl group instead of at the C3-position.

Chemoselective Suzuki–Miyaura cross‐coupling generally requires a designed deactivation of one nucleophile towards transmetallation. Here we show that boronic acids can be chemoselectively reacted in the presence of ostensibly equivalently reactive boronic acid pinacol (BPin) esters by kinetic discrimination during transmetallation. Simultaneous electrophile control allows sequential chemoselective
