The preparations of novel tridentate C,N,S-donor ligand precursors, PhN=C(CMe)(NPh)C=N(CH2)(2)SR [R = CMe3 (2); R = Ph (3)] are described. treatment of 2 and 3 with 1 equiv. of Pd(OAc)(2) affords the orthometallated palladium(II) complexes [PhN=C(CMe2)(N-eta(1)-Ph)C=N(CH2)(2)SR]Pd(OAc) [R = CMe3 (4); R = Ph (5)]. Reaction of 4 and 5 with an excess of LiCl in methanol affords the orthometallated palladium(II) complexes [PhN=C(CMe2)(N-eta(1)-Ph)C=N(CH2)(2)SR]PdCl [R = CMe3 (6); R = PH (7)]. Crystal structures are reoprted for compounds 3 and 4. The application of these novel palladacyclic complexes as catalyses for the Suzuki and Heck reactions with aryl halide substrates was examined.
