ChemInform Abstract: Synthesis of Aryl Triolborates via Nickel‐Catalyzed Borylation of Aryl Halides with 5‐(tert‐Butyldimethylsiloxymethyl)‐5‐methyl‐1,3,2‐dioxaborinane.

Abstract Reaction of the mono‐Tbs protected triol (I) with borane dimethylsulfide generates the title compound which readily undergoes Ni‐catalyzed borylation with various aryl iodides and bromides.
