Unexpected Carbon–Carbon Bond Cleavage in the Reactions of the Pentagonal Bipyramidal Cluster Fe3(CO)6(μ-CO)2[μ3-η4-{RCC(Et)C(Et)CR}] with Styrene. Synthesis and X-ray Structure of Fe3(CO)6[μ3-η4-{EtC2CR}]2 (R = CH3(=CH2))

Microwave‐Assisted Aminocarbonylation of Ynamides by Using Catalytic [Fe3(CO)12] at Low Pressures of Carbon Monoxide

“…First, the active complex "amine-[Fe(CO) 4 ]" [33c, 42] is formed, followed by coordina-tion with the ynamide to give intermediate 17 (or more likely the dimer iron complex 18; Scheme 3). [44,45] After insertion of CO between Fe and C, the nucleophilic attack of nPrNH 2 occurs with simultaneous hydride transfer to Fe. TEA regenerates the [Et 3 N][Fe(CO) 4 ] complex releasing (E)-acrylamide 21.…”
