《Solubility of Phenylboronic Acid and its Cyclic Esters in Organic Solvents》 was written by Leszczynski, Pawel; Hofman, Tadeusz; Sporzynski, Andrzej. Recommanded Product: 24388-23-6 And the article was included in Journal of Solution Chemistry in 2020. The article conveys some information:
The solubilities of phenylboronic acid, its pinacol ester and azaester in organic solvents (chloroform, 3-pentanone, acetone, di-Pr ether and methylcyclohexane) have been determined exptl. by a dynamic method, in which the disappearance of turbidity was determined by measuring of light intensity using a luminance probe. Phenylboronic acid has high solubility in ether and ketones, moderate in chloroform and very low in hydrocarbon. Pinacol ester and azaester show better solubility than the parent acid in all tested solvents. For pinacol ester differences between particular solvents are small, while for azaester the differences are significant. For both esters the highest solubility is observed in chloroform and the lowest in the hydrocarbon. The results have been correlated by the Wilson, NRTL and Redlich-Kister equations. For the phenylboronic acid better correlation of the data is obtained by polynomials in comparison with the above equations. It is connected with addnl. acid-anhydride equilibrium in the system. The influence of polarity of the solvents on the solubility is discussed. In the experiment, the researchers used 4,4,5,5-Tetramethyl-2-phenyl-1,3,2-dioxaborolane(cas: 24388-23-6Recommanded Product: 24388-23-6)
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.Recommanded Product: 24388-23-6
