3. Flash chemistry in organic synthesis
3.1 Microfluidics and chemical selectivity
Selectivity is often used in organic synthesis to refer to the ability of a reaction to lead to the preferential formation of a single product out of several possible ones. However, this definition needs to be clarified to fully understand the phenomena at play in a microreactor. Selectivity is not related to a reaction per se, but should be considered as a system.
This system can be heterogeneous or homogeneous, and usually includes one or more reactants and catalysts, one or more solvents, a headspace (gaseous part of the reactor), a more or less homogeneous temperature, stirring (or not), and a given rate of progress at any given moment, and therefore potentially reaction...
