Layered-double-hydroxide-supported Pd(TPPTS)(2)Cl-2: a new heterogeneous catalyst for Heck arylation of olefins
The Pd(TPPTS)(2)Cl-2(TPPTS: triphenylphosphine trisulfonate, sodium salt) complex is immobilized on layered double hydroxides by the ion-exchange method. This heterogeneous catalyst is successfully used in Heck arylation of olefins. The catalyst can be recycled several times with almost consistent activity.
