A domino reaction is a series of chemical reactions where each reaction triggers the next reaction in the series, like falling dominoes (top). In a domino redox reaction, each reaction causes a structural change that triggers the next redox reaction in the series (bottom). (Takashi Harimoto, et al. Angewandte Chemie International Edition.
