A series of ruthenium complexes of the general formula [RuCl2(L)(NNN)] were synthesized starting from tridentate N,N,N-ligands containing pyridine and allylated pyrazole donor groups and [RuCl2(PPh3)3]. The N,N,N-donors introduced herein are accessible in a few steps from versatile precursors. The primary products, [RuCl2(NNN)(PPh3)], can be converted into the corresponding carbonyl complexes,
以含有吡啶和烯丙基化吡唑供体基团的三齿N,N,N-配体和[RuCl2(PPh3)3]为原料合成了一系列通式[RuCl2(L)(NNN)]的钌配合物。此处介绍的 N,N,N-供体可从通用前体通过几个步骤获得。主要产物 [RuCl2(NNN)(PPh3)] 可以转化为相应的羰基配合物,
