A range of methylthio-substituted acetylenes undergo smooth palladium-catalyzed cross-coupling reactions with functionalized aryl-, heteroaryl-, and alkylzinc reagents using the Pd(OAc)2/DPE-Phos catalytic system at 25 or 50 ˚C without the need for copper salts. alkynes - cross-coupling - organometallic reagents - palladium - zinc
