Nitartion of ferrocene not possible why?
a. Ferrocene cannot be nitrated using the conventional HNO3-H2SO4 mixed acid conditions, even though nitration is an electrophilic aromatic substitution reaction. Explain.
b. In the formation of diacetylferrocene, the product is always the one in which each ring is monacetylated. Thy is no diacetylferrocene produced in which both acetyl groups are on the same aromatic ring?
