(S(N)Ar) reactions. Selective substitution of chloride from cyclopentadienyl(1,4-dichlorobenzene)ruthenium by using piperazine derivatives as nucleophiles is addressed. This selectivity, in combination with further manipulation of the complexes, allows the preparation of unsymmetrically functionalized tetraalkyl-p-phenylenediamine (TAPD) units which are difficult to synthesize by traditional organic
已通过钌活化的亲核芳香族取代(S(N)Ar)反应制备了具有硫代烷基侧链的几个供体-σ受体(D-sigma-A)分子。解决了通过使用哌嗪衍生物作为亲核试剂从环戊二烯基(1,4-二氯苯)钌中选择性取代氯的方法。这种选择性与配合物的进一步处理相结合,可以制备不对称官能化的四烷基对苯二胺(TAPD)单元,这些单元很难通过传统的有机S(N)Ar条件合成。描述了在紫外辐射下苯并菲对芳烃-RuCp体系的分解。
