Lewis acids
Mandarin:
路易斯酸 (lù yì sī suān)
路易斯酸 (lù yì sī suān)
Explanation in English Language (EN):
A Lewis acid is a chemical species that can accept an electron pair. In other words, it is an electron-pair acceptor. Lewis acids play a crucial role in many chemical reactions, including polymerization. They can act as catalysts or initiators in various polymerization mechanisms, such as cationic polymerization and coordination polymerization. Common examples of Lewis acids include metal halides (e.g., AlCl3, BF3) and transition metal compounds.
