Heats of Formation for the Boronic Acids R-B(OH)2 and Boroxines R3B3O3 (R=H, Li, HBe, H2B, H3C, H2N, HO, F, and Cl) Calculated at the G2, G3, and G4 Levels of Theory.

ABSTRACT: Boronic acids (R-B(OH)2) and their boroxine (R3B3O3) dehydration products have emerged as important classes of compounds with a multitude of diverse applications. However, the available heats of formation for these compounds are not always as accurate as would be required for further use. In this study the heats of formation at 298.15 K of R-B(OH)2 and R3B3O3 (R = H, Li, HBe, H2B, H3C, H2N, HO, F, and Cl) have been calculated at the G2, G3[G3B3], and G4 levels of theory and used to determine the enthalpy changes for the dehydration reactions: 3 R-B(OH)2 → R3B3O3 + 3 H2O; comparisons are made with other rigorous level
