In 2011,Chemistry – A European Journal included an article by Chow, Wing-Kin; So, Chau-Ming; Lau, Chak-Po; Kwong, Fuk-Yee. Reference of 2-(3,4-Dimethylphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane. The article was titled 《Palladium-Catalyzed Borylation of Aryl Mesylates and Tosylates and Their Applications in One-Pot Sequential Suzuki-Miyaura Biaryl Synthesis》. The information in the text is summarized as follows:
Palladium-catalyzed borylation with the N-methyl-2-(2′-dicyclohexylphosphino-5′-methoxyphenyl)indole (MeO-CM-Phos) ligand of ten aryl tosylates and twelve aryl mesylates gave the corresponding pinacol aryl boronates in 63% to 97% yield. The reaction conditions are mild and provide excellent functional-group compatibility (e.g., CN, CHO, COOMe, ketone, NH2, benzodioxole, quinolyl, benzothiazole or NH-indole). E.g., reaction of 3-cyanophenyl mesylate with bis(pinacolato)diboron afforded pinacol (3-benzonitrile) boronate in 97% yield. The Pd/MeO-CM-phos catalyst system allows one-pot sequential reactions in the preparation of unsym. biaryls. Four biaryls were prepared by one-pot two-step and one-pot three-step transformations of aryl tosylates and 3-cyanophenol, resp. In the experiment, the researchers used 2-(3,4-Dimethylphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane(cas: 401797-00-0Reference of 2-(3,4-Dimethylphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane)
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. The joining of a fatty acid to glycerol to form a triacylglycerol removes the −OH from the carboxy end of the fatty acid.Reference of 2-(3,4-Dimethylphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane
