(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
