A range of iminophosphine (PN) ligands ((C6H5)2P-C6H4-CH=NR (R=-C6H3(2-CH3)(4-OH) (1a),-CH2CH2C6H4(4-OH) (1b) and-C5H3N(2-CH3) (1c)) have been synthesized starting from 4-amino-3-methylphenol, 4-(2-aminoethyl)phenol and 2-amino-3-methylpyridine with 2-(diphenylphosphino)benzaldehyde. The PN ligands were reacted with Pd(cod)Cl2 to give corresponding new Pd(PN)Cl2 metal complexes, (2a, 2b and 2c). The Heck and Suzuki C-C coupling reactions were examined with catalysts 2a-2c and showed high conversions under the determined conditions with para substituted aryl halides. © 2018, Turkish Chemical Society.
