Abstract

Reaction of [M(NacNac)I(THF)]n (M = Mg, Ca or Yb; n = 1 or 2) with KFp gave Mg(NacNac)Fp(THF) (9, Mg–Fe = 2.6326(4) Å) or [M(NacNac)(μ-Fp)(THF)]2 (M = Ca or Yb (10), no M–Fe bonds); reaction of 10 with [YbFp2(THF)3]2 gave [{Yb(NacNac)(THF)}2(μ-YbFp4)] (Yb–Fe = 2.9758(5)–3.1702(5) Å) containing the first example of a lanthanide bound solely to four transition metals; reaction of 9 with TolNCNTol gave Mg(NacNac){(NTol)2CFp} via the first net insertion of an unsaturated substrate into an alkaline earth-transition metal bond (NacNac = HC{C(Me)N(2,6-C6H3iPr2)}2; Fp = CpFe(CO)2; Tol = 4-C6H4Me).
