Design and synthesis of tetranuclear cluster monophosphine-cyclopalladated ferrocenylpyrimidinone complexes from the palladium-catalyzed hydroxylation of chloropyrimidine.
Hydroxylation of a monomeric triphenylphosphine-cyclopalladated ferrocenylchloropyrimidine [PdCl{[(eta(5)-C(5)H(5))]Fe[(eta(5)-C(5)H(3))-N(2)C(4)H(2)-Cl]}(PPh(3))] with KOH gave the first example of a tetranuclear cluster monophosphine-palladacycle [Pd{[(eta(5)-C(5)H(5))]Fe[(eta(5)-C(5)H(3))-N(2)C(4)H(2)O]}(PPh(3))](4). Additionally, the analogous tricyclohexylphosphine tetranuclear cluster palladacycle has also been successfully synthesized by the same method.
