Two pericyclic reactions involved in the furan synthesis given are to be identified. A mechanism for the transformation also is to be proposed. Concept introduction: In cycloaddition reaction two unsaturated molecules add to one another to yield a cyclic product. If even number of electron pair is involved then thermal reaction occur through antarafacial pathway and photochemical reactions occur through suprafacial pathway. If odd number of electron pair is involved then thermal reaction occur through suprafacial pathway and photochemical reactions occur through antarafacial pathway. To identify: Two pericyclic reactions involved in the furan synthesis given. To propose: A mechanism for the transformation.
