Formation of a [2 + 2]-heterotetranuclear macrocycle from reaction of a platina-homoditopic ligand with iron(ii)
Abstract
Reaction of 4′-(2-propyn-1-oxy)-2,2′:6′,2″-terpyridine (HCCCH2Oterpy) with trans-[PtI2(PEt3)2] regioselectively metallates the
CCH2Oterpy)2(PEt3)2] which, when treated with Fe(II), gives a [2 + 2]-metallocycle.
