A new generation of PNP compounds bearing different diarylphosphine groups were prepared and used as ligands in palladium-catalysed Suzuki cross-coupling reactions. Rates of oxidative addition of iodobenzene to (PNP)Pd[0] complexes were measured using UV spectroscopy. Synergistic effects between the N- and P- substituents were identified and correlated in redox and catalytic chemistry.
制备了带有不同二芳基膦基团的新一代PNP化合物，并将其用作钯催化的铃木交叉偶联反应中的配体。使用紫外光谱法测量了碘苯与(PNP)Pd[0]配合物的氧化加成速率。确定了N-和P-取代基之间的协同效应，并将其与氧化还原和催化化学相关联。
