摘要：

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) angstrom) or [M(NacNac)-(mu-Fp)(THF)](2) (M = Ca or Yb (10), no M-Fe bonds); reaction of 10 with [YbFp(2)(THF)(3)](2) gave [{Yb(NacNac)(THF)}(2)(mu-YbFp(4))] (Yb-Fe = 2.9758(5)-3.1702(5) angstrom) containing the first example of a lanthanide bound solely to four transition metals; reaction of 9 with TolNCNTol gave Mg(NacNac){(NTol)(2)CFp} via the first net insertion of an unsaturated substrate into an alkaline earth-transition metal bond (NacNac = HC{C(Me)N(2,6-(C6H3Pr2)-Pr-i)}(2); Fp = CpFe(CO)(2); Tol = 4-C6H4Me).
