Synthesis and Reactivity of (tricarbonyl)-(η5-2-methylpentadienyl)iron(+1) Cation
Journal of Organometallic Chemistry
The (tricarbonyl)(η5-2-methylpentadienyl)iron(+1) cation was prepared by the protonation of (tricarbonyl)(4-methyl-2,4-pentadienol)iron. Reaction of the cation with H2O, allyl-TMS, NaBH3CN, PPh3, malonate and 3-furyl cuprate gave (η4-1,3-diene)Fe(CO)3 complexes. The regioselectivity for the nucleophilic attack appears to be sterically controlled.
