reaction step

{{short description|Part of a multi-step chemical reaction}}

In chemistry, a reaction step of a chemical reaction is defined as: "An elementary reaction, constituting one of the stages of a stepwise reaction in which a reaction intermediate (or, for the first step, the reactants) is converted into the next reaction intermediate (or, for the last step, the products) in the sequence of intermediates between reactants and products".[http://goldbook.iupac.org/R05178.html "Definition of reaction step"] – IUPAC Gold Book To put it simply, it is an elementary reaction which goes from one reaction intermediate to another or to the final product.
