“…Table II (Entry 1-4) showed the results of the model reaction at different temperature. It was initially performed at 100 C in N 2 and (n-Bu) 3 N as a base. Only 42% yield of the product was obtained after the reaction was performed for 8 h. When the reaction temperature was increased to 110 C, the improved yield of 74% was obtained.…”

“…Table II (Entry 5-9) also showed the yield versus reaction time for the reaction of bromobenzene with styrene catalyzed by PVC-TETA-Pd at 120 C in TBAB using (n-Bu) 3 N as the base. The cross-coupling reaction proceeded slowly within 1 h and the yield was only 9.8%.…”

“…The Heck reaction also holds much promise in the synthesis of intermediates for pharmaceuticals and in preparation of conjugated polymers. 3,4 In view of these, much attention has been paid for the field in recent years. [5][6][7] The commonly used homogeneous catalysts of palladium complexes (PdCl 2 or Pd(OAc) 2 ) with phosphine ligands have high activity in such transformations.…”

Polyvinyl chloride-triethylene-tetramine supported palladium complex (PVC-TETA-Pd) was prepared from polyvinyl chloride via simple method and the production cost of the complex was remarkably low. The complex was an efficient catalyst for Heck reaction. It was active for low activity substrates such as aryl bromides and aryl chlorides. The coupling of bromobeneze with styrene catalyzed by PVC-TETA-Pd afforded 99.8% yield of stilbene under the optimized reaction conditions. PVC-TETA-Pd could catalyze the Heck reactions in the presence of several different kinds of acid-binding agents. Furthermore, the good reusability of PVC-DTA-Pd was also found for Heck reaction.
