A new method for the efficient synthesis of ferrocenylenones was developed. Acryloyl, methacryloyl, crotonyl, cinnamoyl, and &amp / #946 / -methylcrotonyl chlorides reacted with ferrocene in the presence of a Lewis acid (EtAlCl2 or EtAlCl2-Me3Al) to give the corrosponding ferrocenylenones (acryloyl, methacryloyl, crotonyl, cinnamoyl, and &amp / #946 / -methylcrotonylferrocenes) in good isolated yields. Using the Gabriel-Cromwell reaction, acryloyl and crotonoylferrocenes were converted to the novel ferrocenyl substituted aziridines with benzylamine, isopropylamine and furfurylamine. The aziridines were isolated in good to excellent yields.
