  1. Any chemical reaction of the type D01799-0.png, where A, A' and A'' are different chemical species. For example:
    D01799-1.png
    The reverse of disproportionation is called @[email protected] A special case of disproportionation (or 'dismutation') is 'radical disproportionation', exemplified by:
    D01799-2.png
    Reactions of the more general type:
    D01799-3.png
    are also loosely described as radical disproportionations.
