Abstract

Subtle changes in the second coordination sphere of [Cl2bdtFe2(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 Fe2 center can however direct protonation to three different sites: the N in the bis-phosphane, the Fe–Fe bond or the bdt-S.
