可以幫我翻譯也可以發(fā)一篇翻譯給我 Kinetics of the reaction between acetylene and phenylmagnesium bromide were investigated in diethyl ether in the presence of small additions of triethylamine and without a catalyst. The mechanistic scheme suggested by Grignard et al. was supplemented with the reaction of bromomagnesiumacetylene with the Grignard reagent. The rate constants for individual reactions were determined. Triethylamine catalyzes the reactions to different extents, the conversions of bromomagnesiumacetylene being the most susceptible to the catalysis. The possible ways of the action of the catalyst were discussed and the importance of nucleophilic assistance was stressed. © 1999 Elsevier Science S.A. All rights reserved. |

| 研究乙炔與溴化苯鎂在無(wú)催化劑條件下于加入少許三乙胺的乙醚中反應(yīng)的動(dòng)力學(xué)。該反應(yīng)機(jī)理由Grignard等人提出，在溴化乙炔鎂與Grignard試劑反應(yīng)中得到補(bǔ)充說(shuō)明。各自的反應(yīng)常數(shù)已確定。三乙胺在不同程度上催化了這些反應(yīng)，其中溴化乙炔鎂對(duì)其催化作用最為敏感。催化劑可能的作用途徑已被討論，并強(qiáng)調(diào)了親核反應(yīng)的重要作用。 |
