Question:

(a) Ligand 25.19 is used in biphasic catalysis. The IR spectrum of Fe(CO)₄(PPh₃) shows strong absorptions at 2049, 1975 and 1935 cm⁻¹, while that of [Fe(CO)₄(25.19)]⁺ exhibits bands at 2054, 1983 and 1945 cm⁻¹. What can you deduce from these data?

(b) Which of the complexes [X][Ru(25.34)₃] in which X⁺ = Na⁺, [ⁿBu₄N]⁺ or [Ph₄P]⁺ might be suitable candidates for testing in biphasic catalysis using aqueous medium for the catalyst?
