Abstract :A range of iminophosphine insert ignore into journalissuearticles values(PN); ligands insert ignore into journalissuearticles values(insert ignore into journalissuearticles values(C 6 H 5 ); 2 P-C 6 H 4 -CH=NR insert ignore into journalissuearticles values(R=-C 6 H 3 insert ignore into journalissuearticles values(2-CH 3 );insert ignore into journalissuearticles values(4-OH); insert ignore into journalissuearticles values( 1a );, -CH 2 CH 2 C 6 H 4 insert ignore into journalissuearticles values(4-OH); insert ignore into journalissuearticles values( 1b ); and -C 5 H 3 Ninsert ignore into journalissuearticles values(2-CH 3 ); insert ignore into journalissuearticles values( 1c ););  have been synthesized starting from 4-amino-3-methylphenol, 4-insert ignore into journalissuearticles values(2-aminoethyl);phenol and 2-amino-3-methylpyridine with 2-insert ignore into journalissuearticles values(diphenylphosphino);benzaldehyde. The PN ligands were reacted with Pdinsert ignore into journalissuearticles values(cod);Cl 2 to give corresponding new PdLCl 2 metal complexes, insert ignore into journalissuearticles values( 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 arylhalides
