The author of 《Pd-Catalyzed Boroperfluoroalkylation of Alkynes Opens a Route to One-Pot Reductive Carboperfluoroalkylation of Alkynes with Perfluoroalkyl and Aryl Iodides》 were Domanski, Sylwester; Gatlik, Beata; Chaladaj, Wojciech. And the article was published in Organic Letters in 2019. Name: 4-Iodobenzaldehyde The author mentioned the following in the article:
A three-component tandem Pd-catalyzed perfluoroalkylative borylation of terminal and internal alkynes is presented. On the basis of this methodol., the first reductive dicarbofunctionalization of alkynes with two electrophiles (perfluoroalkyl and aryl iodides) through a temperature-controlled sequence of iodoperfluoroalkylation-borylation coupling is developed. This regio- and stereoselective process is easily controllable by a temperature program, providing access to fluoroalkyl-substituted vinyl iodides, vinyl boronates, or olefins from the very same complex reaction mixture (four substrates, catalysts, base, and additives). After reading the article, we found that the author used 4-Iodobenzaldehyde(cas: 15164-44-0Name: 4-Iodobenzaldehyde)
4-Iodobenzaldehyde(cas: 15164-44-0) is used in synthesis of 4-[2-(trimethylsilyl)ethynyl]benzaldehyde, 5,15-dimesityl-10-(3-[2-(trimethylsilyl)ethynyi]phenyl}-20-(4-iodophenyl)porphyrin, and 5,15-dimesityl-10-[3,5-bis{2-[4-(N,N’-difluoroboryl-1,9-dimethyidipyrrin-5-yl)-phenyl]ethynyl}phenyl]-20-(4-iodophenyl)porphyrin.Name: 4-Iodobenzaldehyde
