CpFe(C5H4) 7b). The related complexes RNC4H3(3-PhC═C(H)(C6F5)B(C6F5)2) (R = SiMe3 8, Ph 9) and MeNC4H(2,5-Me2)(3-PhC═C(H)(C6F5)B(C6F5)2) (10) were derived directly from the corresponding reactions of the pyrrole, PhCCH, and B(C6F5)3. In the case of the reaction of N-tert-butylpyrrole, phenylacetylene, and PhB(C6F5)2, phenyl group migration was observed, affording exclusively the species tBuNC4H3(3-PhC═C(H)(Ph)B(C6F5)2)
