PhD Project: New aspects of carboboration and related electrophilic organoboron chemistry

Abstract of Research Project

1,1-Carboboration reactions have been explored intensively in recent years. It is shown to have a great reactivity to cleave C-C= bond, Si-C= bond, P-C= bond and form a new C-C bond , Si-C bond and P-C bond by reacting R-B(C₆F₅)₂ (R = H, Me, Ph, C₆F₅) with substituted dialkynes or alkyne. 1,1-Carboboration yields novel alkenyl boranes which have been employed in metal catalyzed cross-coupling reactions.

We now want to extend this work to the activation of B-C= bonds by treatment of substituted dialkynyl boranes or substituted alkynyl boranes with R-B(C₆F₅)₂ (R = H, Me, Ph, C₆F₅). Attempts to prepare boroles from 1,1-carboboration between R-B(C₆F₅)₂ (R = H, Me, Ph, C₆F₅) and substituted dialkynyl boranes may have an application potential. Such kinds of boroles are electron-deficient building blocks for electron transporting (n-type) materials. In addition, these antiaromatic boroles can split molecular H₂ without use of transition-metal catalysts. Furthermore, we also try to get alkenyl boranes by treatment of substituted alkynyl boranes with R-B(C₆F₅)₂ (R = H,, Me, Ph, C₆F₅).
