In 2022,Firouzeh, Ebrahim; Kazemi, Foad; Gholinejad, Mohammad; Kaboudin, Babak published an article in Journal of Photochemistry and Photobiology, A: Chemistry. The title of the article was 《Visible photosensitized sonogashira-hagihara coupling through in situ prepared palladium catalyst in N,N-dimethylformamide under copper and amine-free additives》.Product Details of 15164-44-0 The author mentioned the following in the article:
In this study, copper and amine-free photosensitized Sonogashira-Hagihara coupling reaction using Pd(OAc)2 and p-nitrobenzophenone in N,N-dimethylformamide(DMF) under blue LED irradiation was reported. Effect of benzophenone, p-methoxybenzophenone and p-nitrobenzophenone as photosensitizers in Sonogashira-Hagihara reaction were studied in which higher yields were achieved using p-nitrobenzophenone. In situ preparation of palladium nanoparticles and the effect of p-nitrobenzophenone were confirmed using UV-Vis and dynamic light scattering (DLS). It was proposed that the DMF affected the formation and stabilization of palladium nanoparticles. Using this catalytic system, aryl iodides and bromides were reacted efficiently with alkynes between 25 and 60°C. In the experimental materials used by the author, we found 4-Iodobenzaldehyde(cas: 15164-44-0Product Details of 15164-44-0)
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.Product Details of 15164-44-0
