Syntheses, characterization and catalytic application of palladacycles containing phosphane or phosphane oxide functionalities

The preparation of ligand precursors PhN=C(CMe2)(NPh)-C= N(CH2)2PPh2 (1) and PhN=C(CMe 2)(NPh)C=N(CH2)2P(O)-Ph2 (2) are described. Treatment of 1 or 2 with 1 molequiv. Pd(OAc)2 affords orthometallated palladium(II) complexes [PhN=C(CMe2)(N- η1-Ph)C=N(CH2)2PPh2]Pd(OAc) (3) as a mononuclear complex or {[PhN=C(CMe2)(N-η1-Ph)C=N- (CH2)2P(O)Ph2]Pd(OAc)}2 (4) as an acetate-bridged dinuclear complex, respectively. Reaction of 3 with excess LiCl in methanol affords a mononuclear palladium(II) complex [PhN=C(CMe 2)(N-η1-Ph)C=N(CH2)2PPh 2]PdCl (5). The crystal and molecular structures are reported for compounds 3-5. Application of these novel palladacyclic complexes to the Suzuki and Heck reactions with aryl halide substrates was examined.
