Webb1 jan. 2024 · The term atom economy (AE) or atom utilization was first coined by Trost [1] and is defined as the theoretical ratio of product mass to mass of substrates in a chemical reaction. Mathematically, AE is calculated by the molecular mass of the product (C) divided by the molecular mass of the reactants (A + B) (Eq. 1) [1].
