| C1592 | Cyclopentadienyliron Dicarbonyl Dimer (1) |
5g |
The present reagent 1 is a binuclear metal carbonyl complex containing cyclopentadienyl ligands and employed as catalyst in carbon-carbon bond forming reactions, such as hydroformylation. Unlike the cobalt carbonyl conventionally employed in so called oxo synthesis, this catalyst is so mild as to yield saturated aldehydes without accompanying alcohols, aldol condensates, etc., as by-products. This reagent 1 is also known as a radical mediator to catalyze the photochemical alkyl addition reactions to some alkenes2a).
