    Functionalization of Tetraorganosilanes and Permethyloligosilanes at a Methyl Group on Silicon via Iridium-Catalyzed C(sp3)–H Borylation
    摘要:
    In the presence of an iridium 3,4,7,8-tetramethyl-1,10-phenanthroline catalyst, a methyl group on the silicon atom of alkyltrimethylsilanes undergoes selective C-H borylation with bis(pinacolato)diboron in cyclooctane at 135 degrees C to give alkyl(borylmethyl)dimethylsilanes. The C-H borylation of tetramethylsilane takes place efficiently at 100 degrees C. Permethyloligosilanes can also undergo C-H borylation without cleavage of the Si-Si bonds.

    chemoselective C(sp3)–H borylation of the methyl group on silicon. The (borylmethyl)silyl group formed by C(sp3)–H borylation is treated with H2O2/NaOH, and the resulting (hydroxymethyl)silyl group is converted into a hydroxyl group by Brook rearrangement, followed by oxidation of the resulting methoxysilyl group under Tamao conditions.
