12-Phosphotungstic acid was used as an efficient, ecofriendly, and air- and moisture-stable catalyst to promote the direct substitution of the hydroxy group of benzylic and allylic alcohols with various β-dicarbonyl compounds. This powerful protocol for carbon–carbon bond-forming reactions provides monoalkylated dicarbonyl compounds in high yields with great efficiency.(© Wiley-VCH Verlag GmbH & Co
12-磷钨酸被用作一种高效、环保、空气和湿气稳定的催化剂,以促进苯甲醇和烯丙醇的羟基被各种β-二羰基化合物直接取代。这种强大的碳-碳键形成反应方案提供了高产率和高效率的单烷基化二羰基化合物。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
