In 2019,Journal of the American Chemical Society included an article by Silvi, Mattia; Aggarwal, Varinder K.. SDS of cas: 24388-23-6. The article was titled 《Radical Addition to Strained σ-Bonds Enables the Stereocontrolled Synthesis of Cyclobutyl Boronic Esters》. The information in the text is summarized as follows:
While radical additions to π-bonds are well established, additions to σ-bonds are far less explored. Authors have found that electron deficient radicals derived from alkyl iodides under visible light irradiation add to the central strained bond of bicyclobutyl (BCB)-boronate complexes and lead to 1,3-alkyl disubstituted cyclobutyl boronic esters in high yields, with full stereospecificity and high levels of stereoselectivity. Novel cyclobutyl-substituted structures, including peptide and steroid boronic ester derivatives can be accessed. Addnl., although the use of electron-rich alkyl iodides as radical precursors was ineffective, an alternative route involving alkylsulfonylation of the BCB-boronate followed by reductive desulfonylation provided access to simple alkyl substituted cyclobutane products. The experimental part of the paper was very detailed, including the reaction process of 4,4,5,5-Tetramethyl-2-phenyl-1,3,2-dioxaborolane(cas: 24388-23-6SDS of cas: 24388-23-6)
4,4,5,5-Tetramethyl-2-phenyl-1,3,2-dioxaborolane(cas: 24388-23-6) can be used as a substrate in the study of Suzuki–Miyaura coupling of various aryl iodides over SiliaCat Pd(0).SDS of cas: 24388-23-6
