Measurement of the coupling constants1J(57Fe–13C) and1J(57Fe–31P) in phosphine and carbonyl complexes of iron

Abstract

¹ J(⁵⁷Fe–¹³C) for [Fe(CO)₅] and ¹J(⁵⁷Fe–³¹P) for [Fe(CO)₄(PEt_nPh_3–n)](n= 1–3) are reported; it is concluded that these complexes probably undergo intramolecular carbonyl exchange at room temperature.
