摘要：
A general and facile visible-light-promoted organic dye catalyzed perfluoroalkylation of hydrazones has been developed using inexpensive and non-toxic Eosin Y as the photoredox catalyst under mild conditions. This reaction protocol exhibits synthetic simplicity, broad scope of substrates, and excellent functional group compatibility. A gram scale synthesis can be also facilitated with a satisfactory yield, which opens up the possibility of practical applications. (C) 2019 Elsevier Ltd. All rights reserved.
