Abstract
Reaction of o-acetoxybenzaldehyde (I) with pyrrole (II) in refluxing acetic acid gives a mixture of the dibenzofuranylpyrromethene (IIIa) and the deacetylation product (IIIb).
ChemInform Abstract
Reaction of o-acetoxybenzaldehyde (I) with pyrrole (II) in refluxing acetic acid gives a mixture of the dibenzofuranylpyrromethene (IIIa) and the deacetylation product (IIIb). These are converted into each other as shown in the reaction scheme. The aldehyde (I) and pyrrole (II) form only approximately 1% of (III), when the reaction is performed in the presence of zinc(II) acetate. (Mechanism, crystal data of (IIIa): orthorhombic, space group P212121, Z = 8).
