Di-μ-hydroxo complexes of palladium(II) with α-diimines

The binuclear hydroxo α-diiminate palladium complexes [Pd2(R′N=CR-CR=NR′)2(μ-OH)2][ClO4]2 (R=H, R′= C6H4Me-o or C6H4Me-p; R=Me, R′=Ph, C6H4Me-o or C6H4Me-p) have been prepared by reacting the corresponding chloro complexes with AgClO4 in Me2CO–H2O. The hydroxo complexes react with the protic electrophiles ethanoic acid, acetylacetone and8-hydroxoquinoline to give the corresponding acetylacetonate, acetate and 8-hydroxiquinolinate complexes.
