Abstract

Iron complexes [BIAN]Fe(I)(η6-toluene) (M1) and [BIAN]FeCl2 (M2) (BIAN=bis(2,6-diisopropylaniline)acenaphthene) were found to be viable catalysts for the regioselective hydroboration of alkynes and alkenes. The hydroboration of alkynes and alkenes in the presence of HBpin and an activator at 70 °C afforded linear vinyl and alkyl boronic esters, respectively. Selectivity up to 98% was observed for alkyl boronic esters and exclusive formation of trans product was observed for vinyl boronic esters.
