Abstract
Subtle changes in the second coordination sphere of [Cl(2)bdtFe(2)-(CO)(4)(Ph2P-CH2-X-CH2-PPh2)] (bdt = benzene-1,2-dithiolate, X = NCH3, NCH2CF3, CH2) that do not influence the electronic character of the Fe-2 center can however direct protonation to three different sites: the N in the bis-phosphane, the Fe-Fe bond or the bdt-S.
