These are the sources and citations used to research friedel-crafts acylation of ferrocene lab report this bibliography was generated on cite this for me on tuesday, october 27, 2015. The friedel-crafts reaction allows for the acetylation of ferrocene via an acetic anhydride using phosphoric acid as a catalyst thanks to the carbonyl group, the subsequent ketone is always less reactive than the original molecule so multiple acetylations do not happen, this also lends to the non-formation of carbocation rearrangements. This breed of reactions were discovered by charles friedel and james crafts in 1877 and are thus are now known as friedel-crafts reactions the reactions can be used in the commencement of either alkyl and acyl groups the acyl group being the key contender in the acetylation of ferrocene.
