Novel tricarbonyldieneiron complexes from the reaction of 2-bromobuta-1,3-diene with carbonylirons

Abstract

Reaction of 2-bromobuta-I ,3-diene with carbonylirons gives the di(tricarbony1dieneiron) : hexacarbonyl-(3.4-dimethylenehexa-1.5-diene)di-iron (111), the di(tricarbony1dieneiron) ketone : hexacarbonyl-(3.5-dimethylenehepta-1.6-dien-4-one)di-iron (V), tricarbonyl-(2-rnethylenebut-3-enoic acid)iron (VI), nonacarbonyl-(3,5-dimethylene-4-methylnona-I ,8-dien-6-yne)tri-iron (IV), tricarbonyl-2-bromobuta-I ,3-dieneiron (I) and tricarbonylbuta-I . 3-dieneiron (11). The mechanism of formation of these complexes is discussed and two novel pairs of diastereomers are described. * We do not yet know whether (111) and (V) are the nzeso or yacenzic forms.

Dendralenes Branch Out: Cross‐Conjugated Oligoenes Allow the Rapid Generation of Molecular Complexity

“…Building on an important early study on the {Fe(CO) 3 } complexes of [4]dendralene (21) by Greene et al, [236] Sherburn and co-workers demonstrated that the tricarbonyliron complexes of [3]-and [4]dendralene can be readily prepared in good yield on a multigram scale through an azabutadienecatalyzed reaction of [Fe 2 (CO) 9 ] with the parent hydrocarbon 11 (Scheme 74). [237] The structures, properties, and reactions of these complexes were studied through a joint computational/experimental approach with Paddon-Row and coworkers.…”
