Wan, Yimei published the artcilePhotocatalytic 1,1-Hydrofluoroalkylation of Alkynes with a Concurrent Vicinal Acylation: An Access to Fluoroalkylated Cyclic Ketones, Category: bromides-buliding-blocks, the publication is Organic Letters (2019), 21(11), 4187-4191, database is CAplus and MEDLINE.
A visible-light-induced 1,1-hydrofluoroalkylation of alkynes with a concomitant vicinal acylation is developed using THF (THF) as the hydrogen atom source. Various fluoroalkylated cyclic ketones, such as indanones, chroman-4-ones, 2,3-dihydroquinolin-4(1H)-ones, and 3,4-dihydronaphthalen-1(2H)-ones, can be efficiently synthesized with excellent trans-diastereoselectivity. The reaction represents the first example of 1,1-hydrofluoroalkylation of alkynes, thus providing a novel method for the construction of fluoroalkanes.
