The stable ferrocenyldiphenylpropargyl cation ( 3 ) is readily and quantitatively generated from the propargylic alcohol 2 with a slight excess of tetrafluoroboric acid in dichloromethane at −78 °C. The cationic species 3 was characterized by 1 H‐ and 13 C‐NMR spectroscopy; nucleophilic trapping reactions gave rise to the formation of ferrocenyldiphenylallenes 9 .
