Organometallic reactions in ionic liquids. Alkylation of aldehydes with diethylzinc
Abstract
The ionic liquids, [bmim][Br] (2a), [bmim][BF4] (2b), [bmim][PF6] (2c), [bdmim][BF4] (8) and [bpy][BF4] (9), were examined as the solvent media for dialkylzinc addition to aldehydes giving the corresponding alcohols. The ionic liquid [bpy][BF4] was found to be the solvent of choice, giving the best yields, easily recovered and reused.
