微波辅助高效分子间多米诺carbopalladation / C ħ官能序列已经发展到访问双-杂芳基的框架在单次操作。该反应涉及通过Pd(0)催化使卤化丙烯酰胺或苯基丙酰胺的碳弹法反应,然后进行直接(杂)芳基化反应,从而获得具有良好收率或优异收率的产品。该方法的综合用途也扩展到了Ugi-加合物作为起始原料的应用。
Azasilines fused nitrogen heterocycles are prepared in excellent yields (from 74 to 98 % according to the structures) for the first time in one operation with high regio‐ and stereoselectivities. The key step consists of an intramolecular palladium‐catalyzed cyclisation reaction of heteroaryl disilane cores, bearing double or triple bond. We first studied the reactivity of pyridyl heterocycles, using xylenes

A new palladium-catalyzed picolinamide (PA)-directed ortho-iodination reaction of epsilon-C(sp(2))-H bonds of gamma-arylpropylamine substrates is reported. This reaction proceeds selectively with a variety of gamma-arylpropylamines bearing strongly electron-donating or withdrawing substituents, complementing our previously reported PA-directed electrophilic aromatic substitution approach to this transformation
