Abstract

The reaction of 3,5-dimethylpyrazolyl-N-isopropylpropanamide (L1) with dichloro(1,5-cyclooctadiene)palladium(II) displaces cyclooctadiene forming Cl2Pd(L1)2. This complex has been characterized by NMR and IR spectroscopy, single crystal X-Ray diffraction, and elemental analysis. It is composed of a square planar Pd with trans L1 ligands attached through a pyrazolyl nitrogen and intramolecular hydrogen bonding between the amide and chloride. Similar reactions were carried out with 3,5-dimethylpyrazolylpropanamide (L2), pyrazolyl-N-isopropylpropanamide (L3), 3-(1H-benzotriazol-1-yl)-N,N-dimethylpropanamide (L4), 3-methylpyrazolylpropanamide (L5), 3-(1H-benzotriazol-1-yl)-2-methylpropanamide (L6), and N-pyrazolypropanamide (L7) presumably forming analogous complexes. This formulation for Cl2Pd(L2)2, Cl2Pd(L3)2, and Cl2Pd(L4)2 is supported by NMR and IR spectroscopy and elemental analysis. The products of the reactions of L5, L6, and L7 are yellow precipitates that are insoluble in most organic solvents. The reaction product of L5 and L6 has been characterized by IR spectroscopy. The reaction product of L7 has been characterized by IR spectroscopy and elemental analysis. Single crystals have not yet been obtained for the products from L2, L3, L4, L5, L6, and L7.
