Herein, we report on the synthesis of alkyl-, aryl-, and alkynyl-substituted chlorotriazines and their ammonium salts, and demonstrate their utility in dehydrative condensation reactions. Although the electrophilicity of these reagents is mainly dependent on the hybridization of the carbon-substituents, it was found that bulky 2,6-dimethylphenyl group-substituted reagents resulted in the highest product yields because of a slight increase in reagent electrophilicity and/or steric hindrance favorable for desired dehydrative condensation reactions.

基于Trizaine的带有碳取代基的脱水缩合剂

在本文中，我们报道了烷基，芳基和炔基取代的氯三嗪及其铵盐的合成，并证明了它们在脱水缩合反应中的效用。尽管这些试剂的亲电性主要取决于碳取代基的杂交，但是发现大体积的2,6-二甲基苯基取代的试剂由于试剂的亲电性和/或空间性略有提高而导致最高的产品收率。不利于所需的脱水缩合反应。
