Abstract

The 1N-(N,N-diethylaminoethyl)-2-arylazoaniline, HL [where HL = ArN = NC 6H 4N(H){C 2H 4N(C 2H 5) 2}; Ar = C 6H 5 (for HL 1), p-MeC 6H 4 (for HL 2) or p-ClC 6H 4 (for HL 3)], ligands were prepared by treating the appropriate 2-(arylazo)aniline with 2-bromo-N,N-diethylethanamine. Reactions of Na 2PdCl 4 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 [(L 3)PdCl] was determined to confirm the characterization. The newly synthesized complex [(L 1)PdCl] was utilized to carry out Suzuki and Heck reactions for a variety of substrates.
