of cationic, half-sandwich ruthenium complexes with the general formula [(η6-arene)RuCl(R1S-C6H4-2-CHNR2)]+ (arene = p-cymene or hexamethylbenzene; R1 = CH2Ph, iPr, or Et; R2 = aryl) have been prepared from the reaction of [(η6-arene)RuCl2]2 with various N,S-donor Schiff base ligands derived from 2-(alkylthio)benzaldehyde and several primary amines. All of the ruthenium complexes were characterized
一系列阳离子,半夹心钌络合物与通式[(η 6 -arene)的RuCl(R 1 S-Ç 6 ħ 4 -2- CHNR 2)] +(芳烃= p -cymene或六甲基苯; R 1 = CH 2 PH,我PR,或Et; R 2 =芳基)已从[(η反应制备6 -arene)的RuCl 2 ] 2与2-(烷硫基衍生的各种N,S供体的席夫碱配体)苯甲醛和几种伯胺。所有钌配合物的特征在于IR,11 H NMR,电化学和UV / Vis光谱学。所述p -cymene络合物经历不可逆的氧化反应而六甲络合物经受准可逆氧化。配体1a和配合物4a,4l和5e的分子结构通过X射线晶体学测定。
