In 2022,Li, Yuting; Kanbur, Uddhav; Cui, Jinlei; Wang, Guocang; Kobayashi, Takeshi; Sadow, Aaron D.; Qi, Long published an article in Angewandte Chemie, International Edition. The title of the article was 《Supported Lanthanum Borohydride Catalyzes CH Borylation Inside Zeolite Micropores》.Product Details of 24388-23-6 The author mentioned the following in the article:
The zeolite-supported lanthanide La(BH4)x-HY30 catalyzes C-H borylation of benzene with pinacolborane (HBpin), providing a complementary approach to precious, late transition metal-catalyzed borylations. The reactive catalytic species are generated from La grafted at the Broensted acid sites (BAS) in micropores of the zeolite, whereas silanoate- and aluminoate-grafted sites are inactive under the reaction conditions. During typical catalytic borylations, conversion to Ph pinacolborane (PhBpin) is zero-order in HBpin concentration A turnover number (TON) of 167 is accessed by capping external silanols, selectively grafting at BAS sites, and adding HBpin slowly to the reaction. The experimental process involved the reaction of 4,4,5,5-Tetramethyl-2-phenyl-1,3,2-dioxaborolane(cas: 24388-23-6Product Details of 24388-23-6)
4,4,5,5-Tetramethyl-2-phenyl-1,3,2-dioxaborolane(cas: 24388-23-6) can be used to prepare sulfinamide derivatives by reacting with diethylaminosulfur trifluoride (DAST) and potassium phenyltrifluoroborate.Product Details of 24388-23-6
