A convenient method for substituting a CO ligand in azacymantrene, (η5- C4H4N)Mn(CO)3 (I), by the interaction of I with PPh3 in the presence of Me3NO has been found. The reactions of (η5-C4H4N)Mn(CO)2PPh3 (II) with electrophiles were studied. The nitrogen atom of the η-pyrrolyl ligand was shown to be the site having the largest basicity with respect to the proton (protonation in CF3CO- OH/CH2Cl2) and
在azacymantrene代配体CO一种方便的方法,(η 5 - Visual C 4 ħ 4 N)的Mn(CO)3(I),通过我PPH的相互作用3在我的存在3 NO已经找到。(η的反应5 -C 4 H ^ 4 N)的Mn(CO)2 PPH 3(II)与亲电子进行了研究。相对于质子,η-吡咯基配体的氮原子被证明是具有最大碱性的部位(CF 3 CO-OH / CH 2 Cl 2中的质子化))和II中的非质子酸(锌,镉,汞,铝,镓,锡,钯盐)。的三核复合体的结构[(PPH 3)(CO)2的Mn(η 5 -C 4 H ^ 4 N)] 2的PdCl 2成立通过X射线研究:该晶体为单斜晶系,一个9.0165(5),b 15.748(1),c 16.179(1)Å,β103.37(1)°,Z = 2,空间群P 2 1 / c ; 钯的配位环境为正方形平面,PdN为2.033(2)和PdCl为2.306(1)。
