Abstract

The much simpler product realized by brominating triethylborane (and similar trialkylboranes containing primary alkyl groups) in the presence of water is evidently the result of a rapid rearrangement of the initial bromination product 5 into the borinic acid 8. The tertiary CY hydrogen of the sec-butyl group undergoes preferential bromination (10). This rearranges to 1 which is oxidized to product 3 (eq 10).
