The present invention addresses the problem of providing a mayenite compound that can induce electron donation reactions H donation reactions deoxygenation reactions and dehydration reactions. The present invention also addresses the problem of providing a multifunctional agent that includes the mayenite compound that does not dissolve in a solvent and that can induce electron donation reactions H donation reactions deoxygenation reactions and dehydration reactions. The present invention also addresses the problem of providing a production method for a mayenite compound containing product. A mayenite compound that is characterized by encapsulating electrons and H. A multifunctional agent that is characterized by containing the mayenite compound I and/or a mixture II of a mayenite compound that encapsulates electrons and a mayenite compound that encapsulates H by being reducible and by having radical elimination activity deoxygenation functionality and dehydration functionality. A production method for a mayenite compound containing product that contains the mayenite compound.
