Synthesis of mono-and 1,1′-bis(3,4,4-trichlorobut-3-enoyl)-ferrocenes and 3,4,4-trichlorobut-3-enoylcymantrene
摘要:
Friedel-Crafts acylation of ferrocene and cymantrene with 3,4,4-trichlorobut-3-enoyl chloride gave the corresponding trichloroallyl terrocenyl and cymantrenyl ketones. The reaction with ferrocene involved either one or both cyclopentadienyl fragments, depending on the reactant ratio. The acylation of acetylferrocene with 3,4,4-trichlorobut-3-enoyl chloride afforded 1-acetyl-1'-(3.4,4-trichlorobut-3-enoyol)ferrocene.
