Selection of a Catalytic System: Choose a catalytic system and reaction that needs validation. Protocol Sharing: The original laboratory shares the detailed experimental protocol, including conditions, catalysts, and reactants. Replication: The secondary laboratory replicates the experiment as closely as possible, using the shared protocol. Data Comparison: Results from both laboratories are compared to check for consistency. Publication: If the results are consistent, they may be published, often with a note on cross-validation.
