Mt. Reetz et G. Lohmer, PROPYLENE CARBONATE STABILIZED NANOSTRUCTURED PALLADIUM CLUSTERS AS CATALYSTS IN HECK REACTIONS, Chemical communications, (16), 1996, pp. 1921-1922
Nanostructured Pd clusters, prepared either electrochemically using a
sacrificial Pd anode or by thermolysis of Pd(O(2)CMe)(2), are stable i
n propylene carbonate even at 140-155 degrees C; such colloidal soluti
ons catalyse Heck reactions in the absence of phosphine ligands.
