A convenient, efficient, and generally applicable method was developed for the synthesis of terminal alkynes from anti‐3‐aryl‐2,3‐dibromopropanoic acids in the presence of DMSO and K2CO3.
Some efficient polymer‐supported palladium catalysts have been synthesized. Their catalytic effects were evaluated in the Heck reaction of iodobenzene with acrylates or styrene. High catalytic activities were achieved with turn over frequencies (TOF) up to 28000 and 6250, respectively. For the reaction of iodobenzene with styrene, high stereoselectivity was obtained. Additionally, the catalysts could...
