Use of allylic triflones for allylation of C-H bonds
摘要:
Allylic triflones react with THF and cyclohexane and related molecules to undergo a trifluoromethyl radical mediated C-H functionalization reaction. Due to polar effects, the reactions benefit from the presence of electron-withdrawing group at the 2-position of the allylic triflones. (C) 1998 Elsevier Science Ltd. All rights reserved.

Chlorine radical, which is classically generated by the homolysis of Cl2 under UV irradiation, can abstract a hydrogenatomfrom an unactivated C(sp3)−H bond. We herein demonstrate the use of HCl as an effective hydrogen‐atom‐transfer catalyst precursor activated by an organic acridinium photoredox catalyst under visible‐light irradiation for C−H alkylation and allylation. The key to success relied
