Oxygenation of aromatic substrates over Pd(II) catalysts bearing BIS(Pyrazol-1-yl)alkanes ligands
Liquid phase oxygenation of 1-tetralin, ethylbenzene, cyclohexane and toluene is described using four catalyst precursors such as: (CH2)n(PzR)PdCl2 (n=1,2; R=H, Me) at T=100 degrees C, P-air = 5.4 atm, substrate/catalyst ratio = 100 for 3 h. It was observed that the type of alkyl bridge between the pyrazolyl ligands has an effect on the catalytic activity.
