Rapid Sonogashira cross-coupling of iodoferrocenes and the unexpected cyclo-oligomerization of 4-ethynylphenylthioacetate

Abstract

A systematic study into the Sonogashira cross-coupling of 1,1′-diiodoferrocene (fcI2) confirms that the Pd(0)–P(tBu)3 system provides a remarkable rate increase over Pd(0)–(PPh3)2. Attempts to couple 4-ethynylphenylthioacetate (2) with fcI2 instead produced a novel cyclic trimer of the former, from syn addition of S–Ac across C[triple bond, length as m-dash]C.
