摘要：

(Chemical Equation Presented) Cooperation is key: N-Butyl-1-benzimidazole- 2-phenylboronic acid hydroxide complex catalyzes the aldol condensation and aldol addition between hydroxyacetone or acetone, and different aldehydes in water. The catalytic activity results from cooperative interactions between the boronate complex and the imidazole function. Aldol condensation gives the unsaturated methyl ketones of acetone, whereas aldol addition predominates with hydroxyacetone. © 2008 Wiley-VCH Verlag GmbH & Co. KGaA.
