  Allenylidene and derived alkynyl complexes of iron(II) with the {FeBr(Et2PCH2CH2PEt2)2}+ centre

  摘要：

  The allenylidene complexes trans-[FeBr{=C=C=C(R)Ph}(dePe)(2)][BPh4] (depe=Et2PCH2CH2PEt2; R=Me 1, Ph 2) were obtained by treatment of a methanolic solution of trans-[FeBr2(depe)(2)] with the appropriate alkynol HCdropC-C(R)Ph(OH), in the presence of Na[BPh4]. The methylallenylidene ligand in 1 undergoes reversible deprotonation (by NaOMe) to yield the enynyl (or ene-yne) complex of iron(II), trans-[FeBr{-CdropC-C(=CH2)Ph}(depe)(2)] 3. The diphenylallenylidene ligand in 2 undergoes regioselective hydride gamma-addition on reaction with K[B{CH(Me)Et}(3)H] to afford the alkynyl complex trans-[FeBr{-CdropC-C(H)Ph-2}(depe)(2)] 4.

Complex 2 (Y = BPh4) also leads to the cationic alkynyl compounds trans-[Fe(NCMe)−C⋮CCPh2(X)}(depe)2][BPh4] (X = NMe2 (6a), NHMe (6b)) and trans-[Fe(NCMe)−C⋮CCPh2(PMe3)}(depe)2]Y2 (Y2 = [BPh4]2 (7a), [BPh4]2-xBrx (7b)), in acetonitrile solution, upon reaction with NHMe2, NH2Me, and PMe3, respectively. The complexes have been characterized by multinuclear NMR
