tetracyclic compounds at ambient temperature. The transformation was initiated by non-activated sp2 C–S bond cleavage along with consecutive alkyne insertions. A double intramolecular reaction of a tetrayne and an intermolecular reaction of monoynes were also available, and the corresponding polycyclic compounds were obtained. Moreover, the obtained cycloadduct showed photo-catalytic activity in benzylic
在环境温度下,Ni 催化的二芳基
硫醚连接的 1,8-二炔分子内反应得到含
硫四环化合物。转化是由未活化的 sp 2 C-S 键断裂以及连续的炔插入引发的。还可以进行四炔的双分子内反应和单炔的分子间反应,得到相应的
多环化合物。此外,所得环加合物在苄基氧化中显示出光催化活性。
