| Abstract |
The reaction of RI (R = Me, Et or Pr) or [Et(3)O][PF6] with [NBu(4)]trans-[Re(CN)(2)(dppe)(2)] (dppe = Ph(2)PCH(2)CH(2)PPh(2)) affords the diisocyanide complexes trans-[Re(CNR)(2)(dppe)(2)]A (R = Me, A = I; R = Pr, A = I-3; R = Et, A = PF6), whereas trans-[Re(CNH)(CNSiMe(3))(dppe)(2)]CF3SO3 is obtained from the reaction with Me(3)SiO(3)SCF(3). The X-ray crystal structure of trans-[Re(CNEt)(2)(dppe)(2)][PF6] was determined. The redox properties of the compounds were studied by cyclic voltammetry and controlled potential electrolysis, and are discussed in terms of the electronic properties of the metal centres and ligands. |
