In organic chemistry. flash vacuum pyrolysis (FVP) is a technique that entails heating a precursor molecule intensely and briefly, often in an argon atmosphere. The method is used to induce transformations that cannot readily be achieved in solution methods such as in refluxing solvents. The technique is uncommon due in part to limitations on the scale on which reactions can be carried out.

In terms of implementation of FVP, two key parameters are the temperature and duration (or residence
