Synthesis of Aryl Triolborates via Nickel-Catalyzed Borylation of Aryl Halides with 5-(tert-Butyldimethylsiloxymethyl)-5-methyl-1,3,2-dioxaborinane

Abstract

The nickel-catalyzed borylation of aryl halides with 5-(tert-butyldimethylsiloxymethyl)-5-methyl-1,3,2-dioxaborinane, prepared in situ, was achieved. The mild reaction conditions allowed common functional groups in the aryl halides to be tolerated. The products of this borylation are potential precursors of aryl triolborates.

carbon-boron bond formation - nickel catalysis - cross-coupling - aryl halides - hydroboranes

<A NAME="RF117511SS-9">9</A> Quite recently, Yamamoto et al. reported on transesterification of pinacol arylboronic esters with 1,1,1-tris(hydroxymethyl)ethane. They developed a one-pot procedure for the synthesis of aryl triolborates from aryl halides through palladium-catalyzed borylation with pinacolborane, see: Li G.-Q. Kiyomura S. Yamamoto Y. Miyaura N. Chem. Lett.  2011,  40:  702

Our attempts to isolate 5-(hydroxymethyl)-5-methyl-1,3,2-dioxaborinane also failed. Furthermore, the use of 1,1,1-tris(hydroxymethyl)ethane instead of 1 for the one-pot nickel-catalyzed borylation was lacking in reactivity and reproducibility (0-50% yield).
