Coordination complexes of palladium dichloride with 4-substituted nitrosobenzenes

Complexes of 4-substituted nitrosobenzenes with palladium dichloride have been prepared and studied by solid state CP/MAS ¹³C NMR spectroscopy. The results obtained are discussed in terms of the unique property of the nitroso group based upon its high p-electron accepting character. It is shown that this property is maintained when the NO group undergoes s_N coordination to palladium in contrast to recent evidence that p_NO coordination to molybenum removes this property. The effect of coordination upon the chemical shifts of the other ring carbons is also discussed. © 1995.
