Ignoring side reactions can be motivated by several factors:
1. Simplification of Analysis: For early-stage research or educational purposes, simplifying the reaction mechanism by ignoring side reactions can make the analysis more manageable. 2. Negligible Impact: If the side reactions produce insignificant amounts of by-products, their effect on the overall process might be minimal, and thus, can be ignored. 3. Focus on Major Pathways: Emphasizing the main reaction pathways can help in understanding the primary mechanism and optimizing the main reaction before addressing side reactions.
