Reaction of palladium bis(acetylacetonate) with diphenylphosphine:spectral studies

摘要

Interaction of palladium bis(acetylacetonate) with diphenylphosphine is studied by NMR,IR,and UV methods.Reaction between reagents takenin equimolar amounsts gives binuclear and trinuclear palladium complexes with bridging diphenylphosphide and the chelateacetylacetonate [Pd(Acac)PPh_2]_2 and [Pd_3(Acac)_2(PPh_2)_4]With excess PPh_2H,the trinuclear palladium complex,whose composition is supposed to be [Pd_3(PPh_2)_4(PPh_2-PPh_2)·C_6H_6],is isolated and characterized on the basis of the spectral data.
