Öğe Efficient synthesis of ferrocenylenones by Friedel-Crafts acylation with EtAlCl2-Me3Al(Elsevier Science Sa, 2005) Doğan, Özdemir; Şenol, Volkan; Zeytinci, Serhat; Koyuncu, Hasan; Bulut, AdnanEfficient synthesis of ferrocenyl en ones using a Friedel-Crafts acylation reaction is described. Acryloyl, methacryloyl, crotonoyl, cinnamoyl, and beta-methylcrotonoyl chlorides react with ferrocene in the presence of a Lewis acid (EtAlC2 or EtAlCl2-Me3Al) to give the corresponding ferrocenyl en ones (acryloyl, methacryloyl, crotonoyl, cinnamoyl, and methylcrotonoylferrocenes) in good isolated yields. Besides ferrocenylenones, chloroactylferrocene is also synthesised by this method. (C) 2004 Elsevier B.V.

Acryloyl- and crotonoy1ferrocenes are brominated first and then reacted with benzylamine, diisopropylamine, and furfurylamine in the presence of triethylamine. The aziridines are obtained in more than 90% isolated yields.
