Murata, Miki; Ueda, Yosuke; Hyogo, Mayu; Kohari, Yoshihito; Namikoshi, Takeshi; Watanabe, Shinji published an article in Journal of Chemical Research. The title of the article was 《Ruthenium-catalysed dehydrogenative C-H borylation of arenes with pinacolborane》.Formula: C14H21BO2 The author mentioned the following in the article:
A ruthenium complex prepared in situ from [RuCl2(p-cymene)]2 and TpMe2K [TpMe2 = hydrotris(3,5-dimethylpyrazolyl)borate] is efficient for aromatic C-H borylation with pinacolborane (4,4,5,5-tetramethyl-1,3,2-dioxaborolane). Arenes were borylated at more electron-rich positions. DFT calculations and kinetic isotope effect experiments suggest that the catalytic cycle should involve an electrophilic aromatic substitution with a borenium cation. In the part of experimental materials, we found many familiar compounds, such as 2-(3,4-Dimethylphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane(cas: 401797-00-0Formula: C14H21BO2)
2-(3,4-Dimethylphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane(cas: 401797-00-0) belongs to hydroxy-containing compounds. Hydroxy groups participate in the dehydration reactions that link simple biological molecules into long chains.Formula: C14H21BO2 The joining of a fatty acid to glycerol to form a triacylglycerol removes the −OH from the carboxy end of the fatty acid.
