We demonstrate filling of single‐wall carbon nanotubes with ferrocene. Encapsulated ferrocenes are utilized as a precursor to secondary inner tubes and iron dopant. The reaction pathway is traced by Raman and photoemission spectroscopy. From a comparison to the inner‐tube growth from C 60 fillers we propose different mechanisms for the inner‐tube growth from fullerene and non‐fullerene precursors. This work pioneers a new chemistry using carbon nanotubes as a nano reaction furnace. (© 2007 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
