摘要
A particular Kaiser oxime resin derived palladacycle is an efficient precatalyst for the Heck reaction with aryl iodides and bromides in DMF and in aqueous solvents under relatively moderate temperatures (110 degrees C and 120 degrees C) and high TON up to 10(5). Poisoning studies indicate that this polymer acts as a precatalyst. The polymer has been reused after recycling with low to moderate leaching of Pd(0).
