Green chemistry metrics

OverviewReaction mass efficiencyMass-based versus impact-based metricsAtom economyPercentage yieldEffective mass efficiencyEnvironmental factorThe EcoScale

The reaction mass efficiency is the percentage of actual mass of desire product to the mass of all reactants used. It takes into account both atom economy and chemical yield. Reaction mass efficiency, together with all metrics mentioned above, shows the “greenness” of a reaction but not of a process. Neither metric takes into account all waste produced. For example, these metrics could present a rearrangement as “very green” but fail to address any solvent, work-up, and e
