Various aliphatic organoboron derivatives were transmetalated to the corresponding dialkylzincs using diethyl- or dimethyl-zinc. This allows an access to zinc reagents not readily available by standard methods. Didecylzinc obtained by this method adds with good enantioselectivity (83% ee) to PhCHO in the presence of catalytic amounts of (1R, 2R)-1,2-bis-(trifluorosulfonamido)cyclohexane.
