Electron Donating Group具体释义
Electron Donating Group的英文发音
例句
- When an H atom or electron donating group ( i.e., CH 3 ) was present at the 3 position, hydroxylation proceeded at the 2 position, but the presence of electron withdrawing substituent groups ( i.e., OH or COOH ) at the 3 position inhibited hydroxylation.
- 当3位上有H原子或供电子基团时,羰基化可在2位上进行,但3位上的吸电子取代基团会抑制羰基化。
- We use N-ethyl carbazole as the electron donating group, and the cyanoacetate as the electron-withdrawing group, connecting the two parts together by converting different II bridge bonds.
- 以n-乙基咔唑作为供电子基团,氰基乙酸为拉电子基团,通过变换不同的∏桥键来合成。
- The photodegradation experiment showed that the introduction of electron withdrawing group on methane chain would improve the photo-stability of the dye, while electron donating group would decrease the photo-stability.
- 三种染料与其母核染料的光降解对比试验说明,甲川链上引入吸电子基团使得染料光稳定性提高,而供电子基团则光稳定性下降。
