Abstract

PURPOSE: To prepare the titled compound useful as a synthetic intermediate of pharmaceuticals, industrial chemicals, etc., economically, by reacting an organic lithium compound with a conjugated diene-tricarbonyliron complex which is an easily available raw material, and treating the product with an acid.
CONSTITUTION: A conjugated diene-tricarbonyliron complex is made to react with an organic lithium compound, e.g. n-butyllithium, phenyllithium, etc. in an inert organic solvent such as ether, usually at -80W-60°C. The reaction product is treated with an acid such as sulfuric acid, or made to react with an alkylating agent and then treated with an acid to obtain the objective compound. The conjugated diene-tricarbonyliron complex can be prepared from a conjugated diene compond and pentacarbonyliron Fe(CO)5 or enneacarbonyldiiron Fe2(CO)9.
