Mj. Ackland et al., CONVERSION OF (2-METHYL-1-AZABUTA-1,3-DIENE)TRICARBONYLIRON(0) COMPLEXES INTO (ENAMINE)TRICARBONYLIRON(0) COMPLEXES, Journal of the Chemical Society. Perkin transactions. I, (4), 1998, pp. 813-817
Treatment of (2-methyl-1-azabuta-1,3-diene)tricarbonyliron(0) complexe
s with lithium diethylamide followed by a proton source leads to the f
ormation of (enamine)tricarbonyliron(0) complexes in good yield.
