Heck reaction catalyzed by palladium supported on LDH-F hydrotalcite: Zhou, Hao; Zhuo, Guang Lan; Jiang, Xuan Zhen (Department of Chemistry, Zhejiang University, Hangzhou 310027, Peop. Rep. China). Journal of Molecular Catalysis A: Chemical, 248(1-2), 26-31 (English) 2006 Elsevier B.V. CODEN: JMCCF2. ISSN: 1381-1169. DOCUMENT TYPE: Journal CA Section: 25 (Benzene, Its Derivatives, and Condensed Benzenoid Compounds) LDH-F hydrotalcite was used, for the first time, as an efficient and selective basic support for the palladium-catalyzed Heck reaction. The ligand-free heterogeneous catalyst Pd/LDH-F exhibits higher activity and selectivity in the Heck reaction of aryl bromides with styrene on a small amt. of palladium (0.1 mol % of Pd). Higher yields than those previously obtained with Pd-contg. layered double hydroxides (LDHs) are reached. The catalyst can easily be sepd. from the reaction mixt. and reused after washing without loss in activity.In this experiment, several chemicals are used like 20909-39-1 and 4333-75-9 The influence of the highly polarized basic fluoride ions on reaction performance is discussed. Moreover, the influence of several fundamental parameters (nature of the support, Mg/Al ratio, property of the Pd complex) on the reactivity is also discussed. .
