Reaction of [(畏⁵-C₅H₄Me)₄Fe₄(HCCH)(HCC鈥揃r)](PF₆) with ^tBuNH₂ forms [(畏⁵-C₅H₄Me)₄Fe₄(HCCH)(HCC鈥揘H^tBu)](PF₆), of which one electron oxidation leads to carbon鈥揷arbon bond cleavage to give [(畏⁵-C₅H₄Me)₄Fe₄(HCCH)(渭₃-CH)(渭₃-CNH^tBu)](PF₆)₂, and further treatment with 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) affords [(畏⁵-C₅H₄Me)₄Fe₄(HCCH)(渭₃-CH)(渭₃-畏¹-CN^tBu)](PF₆). Thus, the HCCBr group is converted to ^tBuNC and CH groups on the redox-responsive tetrairon core.
