  • Effect of Reaction Parameters on the Synthesis of 5

    The influence of crucial reaction parameters on Knoevenagel condensation in planetary ball mills was investigated. Rotation frequency (νrot), milling ball diameter (dMB), milling ball filling degree (Φ), and beaker size had obvious influences on yield. It was found that higher νrot, lower dMB, milling beakers with larger diameter, and a Φ of ∼0.3 are advantageous for the reaction.
