2021-06-27 20:04 The reaction mechanism is of great significance in organic chemistry. Through the reaction mechanism, it is possible to (1) find the laws of organic reactions to optimize the reaction efficiency and increase the reaction yield; (2) design new reactions to expand the application range of the reaction and so on. The complete reaction mechanism usually needs to consider the breakage and formation of bonds and the formation of corresponding transition states, and sometimes also need to consider the catalyst and the stereochemistry of the reaction.
