Organoboranes. 55. An Improved Procedure for the Conversion of Representative Achiral and Chiral Monoalkyl-, (E)- and (Z)-Alkenyl-, and Arylboronates into the Corresponding Organldichloroboranes
Abstract
Chiral alkylboronates of essentially 100% enantiomeric purity prepared by asymmetric hydroboration of readily available prochiral olefins were effectively converted into the corresponding chiral monoalkyldichloroboranes by treatment with boron trichloride (1 M solution in dichloromethane) in the presence of a catalytic amount of anhydrous ferric chloride (3 mole %). This procedure works equally well for the conversion of E- and Z-alkenylboronates, phenylboronates and tert-butylboronates into the corresponding dichloroboranes respectively.
