Dimerization of Terminal Aryl Alkynes Catalyzed by Iron(II) Amine-Pyrazolyl Tripodal Complexes with E/Z Selectivity Controlled by tert-Butoxide

摘要

The catalytic activity of iron(II) complexes with functionalized amine-pyrazolyl tripodal ligands toward dimerization of terminal alkynes in the presence a base (KO~(t) Bu or NaO~(t) Bu) has been studied. An unusual E /Z selectivity of the reaction determined by tert -butoxide was observed.
