Cyclobutenes with 2-pyridylmethylene groups at the 3 position underwent an intermolecular alkyne insertion reaction in the presence of a rhodium(I) catalyst at 170 °C to afford substituted benzenes. Among the different 2-pyridylmethylene groups examined, 3-methyl-2-pyridyl derivatives showed superior activity and readily coupled with various alkynes, including sterically demanding, heteroaromatic and
在170℃下,在铑(I)催化剂存在下,在3位具有2-吡啶基亚甲基的环丁烯进行分子间炔烃插入反应,得到取代的苯。在所研究的不同的2-吡啶基亚甲基中,3-甲基-2-吡啶基衍生物显示出优异的活性,并易于与各种炔烃偶联,包括空间需求的,杂芳族和末端炔烃。
