Abstract

The behaviour of the neutral alkynyl complexes trans-[FeBr(L)(depe)2] (L = -C=C-C(=CH2)Ph 1a, -C=C-CPh2(H) 1b; depe = Et2PCH2CH2PEt2) is studied by cyclic voltammetry and the electrochemical PL and EL ligand parameters for the alkynyl ligands are estimated showing that they behave as very strong net electron-donors.

Keywords: alkynyl, anodic behaviour, electrochemical ligand parameters, cyclic voltammetry.
