摘要：
A novel class of water soluble palladium complexes with recognition abilities based on functionalized)3 cyclodextrinhas been synthesized. The complex demonstrated high catalytic activity and a supramolecular platform for phosphine-free Mizoroki-Heck cross-coupling reactions in water. The efficient arylation of alkenes was carried out using different iodo- and bromo-arenes with good to excellent yields (up to 96%). The advantages, like recyclability of catalysts, operational simplicity and accessibility in aqueous medium, make this protocol eco-friendly. (C) 2016 Elsevier Ltd. All rights reserved.
