A process for making organoboron compounds is disclosed in which at least one organic compound having at least one Cl, Br, or I atom or at least one nucleophilic leaving group substituent is reacted with at least one boron-containing reagent represented by the chemical formula (IA) or (IB): B(YR1)3 (IA) [Cat]n+[B(YR1)4-]n (IB) in the presence of at least one oxidizable metal or oxidizable metal complex, wherein each Y independently represents an oxygen atom, a sulfur atom, or NR-, each R1 and each R independently represents an organic moiety comprising up to 15 carbon atoms and, optionally, one or more hetero atoms, Cat is a cation or mixture of cations, and n is a positive number in the range from 1 to 3. The organoboron products obtained by this process are useful for conducting coupling reactions and reactions with aldehydes. Due to their selectivity, such reactions may be conducted in protic solvents, such as water and alcohols, and sensitive functional groups in the reactants are maintained in the final product. The organoboron products are stable, so that they maintain their activity during storage.
