A number of secondary aminocarbenes of the type -[(eta(5)-C5H5)Fe(CO)(
PPh3){=C(CH2R1)(NHR2)}]+BF4- were synthesised in very good yield [66-9
9%, R-1 = H, Me or Pr; R-2 = H, Me, Pt, CHMe2, CH2Ph, CH(Me)Ph, CH2CH=
CH2 or CH2CH2OH]. The absolute configuration of one of the carbenes wa
s established by a single-crystal X-ray diffraction experiment. The ch
emistry of the carbene complexes was investigated.
