A radical 1,2,4-trifunctional reaction of thiosulfonate to unactivated olefin is achieved by a migration strategy under mild conditions. In this reaction, the more unstable primary free radicals are in situ generated after the migration of heteroaryl groups in the presence of DABCO. This trifunctionalization of unactivated olefins involves two C–S bond formations and one C–C bond formation.
通过温和条件下的迁移策略实现了硫代磺酸盐与未活化烯烃的自由基1,2,4-三官能反应。在该反应中,杂芳基在 DABCO 存在下迁移后原位产生更不稳定的伯自由基。未活化烯烃的三官能化涉及两个 C-S 键形成和一个 C-C 键形成。
