Carbanion addition to a metalated acetaldehyde. A new regiospecific alkene synthesis
The reaction of 2-[(dicarbonyl)(η 5-cyclopentadienyl)iron]acetaldehyde with organolithium and Grignard reagents results in efficient addition to the aldehyde carbonyl. The intermediate alkoxides have been treated with tetrafluoroboric acid to give high yields of isolated η 2-alkene complexes of the...

Summary: | The reaction of 2-[(dicarbonyl)(η
5-cyclopentadienyl)iron]acetaldehyde with organolithium and Grignard reagents results in efficient addition to the aldehyde carbonyl. The intermediate alkoxides have been treated with tetrafluoroboric acid to give high yields of isolated η
2-alkene complexes of the dicarbonyl(η
5-cyclopentadienyl)iron cation. Using this procedure the following alkenes were produced as complexed ligands to iron in 50–90% yield: propene, 1-hexene, 3-methyl-1-pentene, 3,3-dimethyl-1-butene, 1,3-butadiene, and styrene. |
