摘要
The 1N-(N,N-diethylaminoethyl)-2-arylazoaniline, HL [where HL = ArN = NC 6 H 4 N(H){C 2 H 4 N(C 2 H 5 ) 2 }; Ar = C 6 H 5 (for HL 1 ), p-MeC 6 H 4 (for HL 2 ) or p-ClC 6 H 4 (for HL 3 )], ligands were prepared by treating the appropriate 2-(arylazo)aniline with 2-bromo-N,N-diethylethanamine. Reactions of Na 2 PdCl 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. © 2011 Elsevier Ltd. All rights reserved.
