G. Fitzsimons et al., A DRAMATIC SHIFT FROM MULTIPLE TO SIMPLE EXCHANGE IN THE CYCLOPENTANED-2 PROBE REACTION ON PALLADIUM CATALYSTS/, Catalysis letters, 45(3-4), 1997, pp. 187-191
Electron deficient active sites in Pd catalysts, either as films or on
supports, are deliberately generated by calcining in O-2 at high temp
erature followed by the mildest possible reduction (with the reaction
mixture itself), and are manifested by a marked shift from multiple to
simple exchange in the cyclopentane/D-2 probe reaction.
