ИСТИНА

Organoboranes,commercially available or easily prepared via hydroboration of olefins, represent a very attractive source of alkyl radicals.3 We reported here, that trialkylboranes4 can be used in Minisci type reactions using either either air or iron(II)/tert-butylhydroperoxide as co-reagents. This process compares well will the methods reported in the literature in term of yield and efficiency and, due to the versatility of the hydroboration reaction, allows the introduction of a broad variety of substituents.
