Pd(II) complexes of novel phosphine ligands: Synthesis, characterization, and catalytic activities on Heck reaction. (2nd July 2016) - Altan, Orhan
GRAPHICAL ABSTRACT: ABSTRACT: Novel phosphine oxides, (((3-methylpyridin-2-yl)amino)methyl)diphenylphosphine oxide (1 ) and diphenyl((pyrazin-2-ylamino)methyl)phosphine oxide (2 ), were synthesized and characterized. Phosphines ligands (3 and4 ) were obtained by the reduction of1 and2 with AlH3, monitored by 31 P NMR spectroscopy. Pd(II) complexes of3 and4 were synthesized and characterized (5 and6 ). The catalytic activity of5 and6 was tested on the reaction of styrene with both activated and deactivated aryl bromides in air. The results of the catalytic experiments were discussed through DFT calculations.
