Chloride Method

Acetylations of 3-ferrocenyl-1-methylpyrrole as well as 3-cyano-4-ferrocenylpyrrole and 3-cyano-4-ferrocenyl-1-methylpyrrole were performed. The course of the acylation is highly dependent on the acylation agent, that is acetyl chloride/aluminum chloride (method A), trifluoroacetic anhydride-acetic acid mixture (method B) or acetic anhydride/Sc(OTf)3 (method C). Method A gives the acetylation on ferrocene moiety, method B affords the trifluoroacetylation on pyrrole moiety and method C affords pyrrole moiety acetylation. Vielsmeier-Haack formylation gives the products of substitution on pyrrole moiety.

Plausible Mechanism

The reactions between aluminum tertiary butoxide and acetyl chloride have been studied. The addition of 1 mole of acetyl chloride to aluminum tertiary butoxide forms monochloride ditertiary butoxide, which, with another mole of acetyl chloride, appears to give the dichloride monotertiary butoxide derivatives. Further, these products appear to react with tertiary butyl acetate formed in the reaction itself, giving acetate derivatives. The above is confirmed by a detailed study of the reactions between aluminum chloride and tertiary butyl acetate, which have been found to result in the acetate derivatives. A plausible mechanism has been suggested.

Amino Derivatives

The alkylation of P-di-t-butylbenzene with excess t-butyl chloride in the presence of aluminum chloride in the cold produces a new aromatic hydrocarbon, m.p. 218.5–219°. Evidence is given for the presence of an alicyclic nucleus in this hydrocarbon which analyzes for C22H34. The preparation of nitro and amino derivatives from this hydrocarbon is described. The alkylation of benzene under similar conditions yielded some 1,3,5-tri-t-butylbenzene, and an improved method of preparation of this hydrocarbon from P-di-t-butylbenzene is given.
