In 2022,Tu, Chenhao; Ma, Nana; Xu, Qingli; Guo, Wenyue; Zhou, Lanxin; Zhang, Guisheng published an article in International Journal of Quantum Chemistry. The title of the article was 《Computational study on the mechanism of metal-free photochemical borylation of aryl halides》.Category: alcohols-buliding-blocks The author mentioned the following in the article:
C-radical borylation is a significant approach for the construction of carbonboron bond. Photochem. borylation of aryl halides successfully applied this strategy. However, precise mechanisms, such as the generation of aryl radicals and the role of base additive (TMDAM) and water, remain controversy in these reactions. In this study, photochem. borylation of aryl halides has been researched by d. functional theory (DFT) calculations Indeed, the homolytic cleavage of the CX bond under irradiation with UV-light is a key step for generation of aryl radicals. Nevertheless, the generation of aryl radicals may also undergo the process of single electron transfer and the heterolytic carbonhalogen bond cleavage sequence, and the latter is favorable during the reaction. The experimental process involved the reaction of 4,4,5,5-Tetramethyl-2-phenyl-1,3,2-dioxaborolane(cas: 24388-23-6Category: alcohols-buliding-blocks)
4,4,5,5-Tetramethyl-2-phenyl-1,3,2-dioxaborolane(cas: 24388-23-6) also known as boronate ester, is generally used in metal-catalyzed C-C bond formation reactions like Suzuki–Miyaura reaction.Category: alcohols-buliding-blocks
