Pm. Branton et al., Conversion of (2-methyl-1-azabuta-1,3-diene)tricarbonyliron(0) complexes into tertiary (enamine)tricarbonyliron(0) complexes, J ORGMET CH, 613(2), 2000, pp. 200-207
Treatment of (2-methyl-1-azabuta-1,3-diene)tricarbonyliron(0) complexes wit
h lithium diethylamide followed by a methyl iodide, benzyl bromide or allyl
bromide quench leads to the formation of tertiary (enamine)tricarbonyliron
(0) complexes in good yield. The crystal structures of two complexes, (2-(N
-methyl-N-(4-methoxyphenyl)amino)-4-phenylbuta-1,3-diene)tricarbonyliron(0)
(19) and (2-(N-allyl-N-isopropylamino)-4-phenylbuta-1,3-diene)tricarbonyli
ron(0) (24) are reported. (C) 2000 Elsevier Science B.V. All rights reserve
