Abstract
The first dimesitylboryl substitution of aryl halides with a silylborane bearing a dimesitylboryl group in the presence of alkali-metal alkoxides is described. The reactions of aryl bromides or iodides with Ph2MeSi−BMes2and Na(OtBu) afforded the desired aryl dimesitylboranes in good to high yields and with high borylation/silylation ratios. Selective reaction of the sterically less-hindered C−Br bond of dibromoarenes provided monoborylated products. This reaction was used to rapidly construct a D-π-A aryl dimesityl borane with a non-symmetrical biphenyl spacer.
