The reaction between Ru-2(ap)(4)Cl (ap = 2-anilinopyridinate) and LiC C-4-Ph-P(O)(O'Bu)(2) afforded Ru-2(ap)(4)-C C-4-Ph-P(O)(O'Bu)(2) (1), which was further reacted with LiC C-4-Ph-S(CH2)(2)SiMe3 to yield trans-(4-Me3Si(CH2)(2)S-Ph-C C)-Ru-2(ap)(4)-C C-4-Ph-P(O)(O'Bu)(2) (2). trans-Ru-2(DMBA)(4)(C C-4-Ph-P(O)(O'Bu)(2))(2) (3; DMBA = N,N'-dimethylbenzamidinate) was obtained from the reaction between Ru-2(DMBA)(4)(NO3)(2) and either HC C-4-Ph-P(O)(O'Bu)(2) in the presence of Et3N or LiC C-4-Ph-P(O)(O'Bu)(2). Compounds 1-3 were characterized by HR-MS, X-ray diffraction, and voltammetric techniques, which revealed the retention of essential characteristics in molecular and electronic structures upon the phosphonate capping.
