Tertiary amines
基本例句
叔胺类物质
We discovered that various nucleophiles could react with aziridines in the presence of tertiary amines, in which DABCO is the most efficient catalyst.在亲核试剂对氮杂环丙烷开环反应的研究中，我们发现三级胺能作为一种有机催化剂，有效催化此类反应的进行，经过实验的探索和研究，我们发现在各种三级胺中，DABCO最优。
Tertiary amines, although basic, fail to yield amides, presumably because they cannot lose a proton, after attaching themselves to carbon or to sulfur.叔胺虽然呈碱性，但不能产生酰胺，这大概是因为当它们连在碳或硫上之后，无法失去一个质子以稳定产物的缘故。
