The new azo ligand 2-(2-(p-tolyldiazenyl)phenylamino)acetic acid, H2L, [formulated as H3CC6H4-N = N-C6H4-N(H)(CH2COOH)] was prepared. Reaction of H2L with Na2PdCl4 afforded the orthopalladated mononuclear [(HL)PdCl] complexes. The uncoordinated free dangling carboxylic acid function was recognized and confirmed by X-ray crystallographic studies. The [(HL)PdCl] complex was immobilized on Merrifield resin tethering with the free carboxylic acid function of the complex. Catalytic activity of orthpalladated [(HL)PdCl] complex in homogeneous media and Merrifield supported immobilized complex in heterogeneous phase, toward Suzuki cross-coupling reactions, were examined.
