Synthesis and characterisation of the aminocarbene complexes [η5-C5H5Fe(CO)(PPh3){=C(NHR 2)(CH2R1)}]+BF4- [R1 = H, Me or Pr; R2 = H, Me, Et, CHMe2, CH2Ph, CH(Me)Ph, CH2CH=CH2 or CH2CH2OH]

A number of secondary aminocarbenes of the type (RS)-[(η5-C5H5)Fe(CO)(PPh 3){=C(CH2R1)(NHR2)}] +BF4- were synthesised in very good yield [66-99%, R1 = H, Me or Pr; R2 = H, Me, Et, CHMe2, CH2Ph, CH(Me)Ph, CH2CH=CH2 or CH2CH2OH]. The absolute configuration of one of the carbenes was established by a single-crystal X-ray diffraction experiment. The chemistry of the carbene complexes was investigated.
