The yields could also be improved by using an excess of BR-9-BBN. However, this is desirable only when the alkyl group represents an easily available reagent and it is desirable to convert as much as possible of a valuable a-bromo ketone to product. Obviously, in cases where it is the alkyl group that is the valuable intermediate, such an excess should be avoided. In contrast to the earlier procedure, where no product was ...
