An Efficient and Recyclable Ligand-Free PEG1000-DIL/Toluene Temperature-Dependent Biphasic System for Palladium Catalysed Heck Reactions

Thermoregulated Aqueous Biphasic Catalysis of Sonogashira Reactions

A water-based thermoregulated system for Pd-catalyzed Sonogashira reactions is presented, which allows for not only a highly efficient homogeneous catalytic reaction, but also an easy separation/recovery of the catalyst. The novel catalytic system exhibits high efficiency and excellent reusability. In addition, the Sonogashira reactions are performed with Pd(OAc)2 without a copper co-catalyst.

Thermo-regulated phase separable catalysis (TPSC)-based atom transfer radical polymerization in a thermo-regulated ionic liquid

A thermo-regulated phase separable catalysis (TPSC) system for AGET ATRP based on a thermo-regulated ionic liquid was developed for the first time. The corresponding transition metal catalysts could be easily recovered and reused several times with negligible loss of catalytic activity.
