• Borinic acid - Wikipedia

    IUPAC naming for Borinic acid is a unique name for acid. The anhydrides are named diboroxanes, H 2 BOBH 2, as the base compound and H being able to be substituted, e.g. tetraethyldiboroxane, as the anhydride for diethylborinic acid.Organic naming standard in the bluebook allows skeletal replacement naming where the name is shorter, 3-borapentan-3-ol versus diethyl borinic acid.

  • C-H Bond Functionalization in Complex Organic Synthesis ...

    Direct and selective replacement of carbon-hydrogen bonds with new bonds (such as C–C, C–O, and C–N) represents an important and long-standing goal in chemistry. These transformations have broad potential in synthesis because C–H bonds are ubiquitous in organic substances. At the same time, achieving selectivity among many different C–H bonds remains a challenge.

  • Thallium hydride - Wikipedia

    Thallium hydride is mainly produced for academic purposes. Thallium hydride is the simplest thallane. Thallium is the heaviest member of the Group 13 metals; the stability of group 13 hydrides decreases with increasing periodic number. This is commonly attributed to poor overlap of the metal valence orbitals with that of the 1s orbital of Hydrogen.
