to the efficient and completely regioselective generation of aromatic CC and CN bonds. The method is simple, rapid, general and inexpensive, and can be performed without the use of dried solvents. Most of the synthetized compounds are new and in many cases the work‐up required only filtration. Furthermore, this is the first example of the use of a Lewis acid as a catalyst for heteroarylation, vinylation
在催化量的三氯化铟的存在下,对一系列卤化的氮杂环和不同种类的亲核试剂进行聚焦微波辐照可有效且完全区域选择性地生成芳族CC和CN键。该方法简单,快速,通用且廉价,并且可以在不使用干燥溶剂的情况下进行。大多数合成的化合物都是新化合物,在许多情况下,仅需过滤即可进行后处理。此外,这是使用路易斯酸作为催化剂在π缺陷杂环底物上进行杂芳基化,乙烯基化和胺化反应的第一个例子。
