; The square-planar palladium complexes trans-[PdCl2 (PPh2-CH2-2,4,6-C6H2Me3)2] (1) and trans-[PdCl2 (η2-PPh2-CH2-2,4,6-C6HMe3-CH2-2,4,6-C6HMe3-CH2-PPh2)] (2) have been synthesized from [PdCl2 (cod)] (cod = 1,5-cyclooctadiene) and the corresponding new phosphine or diphosphine ligands. The single-crystal X-ray structure analysis reveals for both complexes a trans arrangement of the two chlorine and of the two phosphorus atoms. In both cases, ortho-metallation leading to palladacycles is not possible, since all ortho positions in the benzylic rings of 1 and 2 are blocked by methyl substituents. Both complexes are found to catalyze Suzuki cross-coupling reactions of deactivated and even bulky arene substrates. - PublicationAccès libreDouble HCl elimination and configuration change in the square-planar palladium complex trans-[{(Ph2PC6H4CONH) 2C6H4}PdCl2] under Suzuki conditions: Isolation and molecular structure of cis-[{(Ph2PC6H4CON)2C6H4}Pd](2006)
