1. 針對實(shí)驗(yàn)中對甲基苯磺酸鹽的問題，我們以2-naphthol, adenine and a benzaldehyde三組分反應(yīng)為模板反應(yīng)，做了兩組平行實(shí)驗(yàn)，其中一組反應(yīng)后用了堿水中和產(chǎn)率為80.3%，另一組沒用堿水中和產(chǎn)率為80%，產(chǎn)率相差不大，而且催化劑的用量又少，所以我認(rèn)為沒必要中和反應(yīng)。 2. 一些產(chǎn)物為中等產(chǎn)率，通過TLC監(jiān)測發(fā)現(xiàn)還是沒有反應(yīng)的原料，我們把這些反應(yīng)延長反應(yīng)時(shí)間至72小時(shí)，產(chǎn)率基本沒有發(fā)生沒化，所以最后我就結(jié)束反應(yīng)。 |

1. To address the issue of salt of p-toluenesulfonate, we did a model reaction with 2-naphthol, adenine and a benzaldehyde as the reactants in two parallel experiments: one with base neutralization, and one without. The yields are 80.3 and 80.0%, respectively, showed little difference. Since the amount of catalyst is very small, it is our view that there is no need to neutralize the reaction. 2. For some reactions with moderate yields, it is because that the reactants did not participate the reaction, as shown with TLC analysis. Prolong the reaction time up to 72 hrs did not improve the yields. Therefore the reactions were stopped. |
