achieved under photoirradiation, in which 1,2-bis(phenylsulfonyl)-2-propene acts as an allyl source and 5,7,12,14-pentacenetetrone (PT) works as a C–H bond-cleaving catalyst. A variety of substances, including alkanes, carbamates, ethers, sulfides, and alcohols, were chemoselectively allylated in a single step under neutral conditions. The present transformation is catalyzed solely by an organic molecule
在光辐照下实现了在非酸性C(sp 3)-H键处烯丙基的催化引入,其中1,2-双(苯磺酰基)-2-丙烯为烯丙基源,5,7,12,14- pentacenetetrone(PT)可作为C–H键裂解催化剂。在中性条件下,只需一步即可将烷烃,氨基甲酸酯,醚,硫化物和醇等多种物质化学选择性烯丙基化。本转化仅由有机分子PT催化,并且在以烷烃为起始物质的情况下,即使在可见光照射(425nm)下也能顺利进行。
