Abstract
The 1N-(N,N-diethylaminoethyl)-2-arylazoaniline, HL [where HL=ArN=NC6H4N(H){C2H4N(C2H5)2}; Ar=C6H5 (for HL1), p-MeC6H4 (for HL2) or p-ClC6H4 (for HL3)], ligands were prepared by treating the appropriate 2-(arylazo)aniline with 2-bromo-N,N-diethylethanamine. Reactions of Na2PdCl4 with HL afforded the [(L)PdCl] complexes. HL binds palladium(II) in a tridentate fashion (N,N,N), forming a new diazoketiminato chelate. The X-ray structure of [(L3)PdCl] was determined to confirm the characterization. The newly synthesized complex [(L1)PdCl] was utilized to carry out Suzuki and Heck reactions for a variety of substrates.
