Selective O-borylation of silanols with diborons took place in the presence of Pd catalysts to give the corresponding boryl silylethers in high yields.
A methylgroup of methylchlorosilanes undergoes C-H borylation in an iridium-catalyzed reaction with bis(pinacolato)diboron in cyclohexane at 80 °C, giving (borylmethyl)chlorosilanes selectively.
