(a) Interpretation: The explanation for the conversion of A to B is to be stated. Concept introduction: Alkene metathesis generally known as olefin metathesis occurs in the presence of Grubbs catalyst. The ring-closing metathesis (RCM) by Grubbs catalyst occurs if the starting material is diene. This reaction is facilitated under the high-dilution condition as it favors intramolecular metathesis instead of intermolecular metathesis.
