effectively transfer the borylene ligand to other transition metal complexes by replacing one or two carbonyl ligands upon irradiation of the reaction mixture with UV light. This borylenetransfer reaction led to the formation of new terminal and bridging borylenecomplexes which cannot be formed by the corresponding salt elimination reactions, including a rare example of a bis(terminal borylene) complex

Syntheses of the phosphaalkyne complexes [Ni2(η5-C5H5)2(tBuCP)] and [CoNi(η5-C5H5)(CO)3(tBuCP)] are described. Adducts of the latter with [W(CO)5] and [Mn(CO)2(η5-C5H5)] are also reported. The reactions of tBuCP with [CoMn(CO)9] or [RuCo2(CO)11] lead to the disproportionation products [Co2(CO)6(tBuCP)] and [Mn2(CO)10] or [Ru3(CO)10], respectively.
所述phosphaalkyne络合物的合成[镍2(η 5 -C 5 H ^ 5)2(吨BuCP)]和[的CoNi(η 5 -C 5 H ^ 5)(CO)3(吨BuCP)]中描述。后者与[W(CO)的加合物5 ]和[锰(CO)2(η 5 -C 5 H ^ 5)]也报道。的反应吨BuCP与[期CoMn(CO)9 ]或[的RuCo 2(CO)11 ]导致歧化产物[CO 2(CO)6(t BuCP)]和[Mn 2(CO)10 ]或[Ru 3(CO)10 ]。
Synthesis of Triangular and Tetrahedral Heteronuclear Metal Clusters Using Hydride Complexes of Cyclopentadienylrhodium and -ruthenium as the Precursors
Photochemical and/or thermal reactions of Cp*Rh(H)2(SiEt3)2 (Cp* = η5-C5Me5) with the dimeric metal complexes [CpNi(CO)]2 (Cp = η5-C5H5), [CpCo(NO)]2, [CpRu(CO)2]2, and [CpFe(CO)2]2 yielded the trinuclear complexes (Cp*Rh)(CpNi)2(CO)2 (3), (Cp*Rh)(CpCo)2(NO)2 (4), (Cp*Rh)(CpM)2(CO)4 (5a, M = Ru; 5b, M = Fe), respectively, while the reaction with [CpMo(CO)2]2 gave the tetranuclear unsaturated complex
Reaction of mesitylenetetracobaltnonacarbonyl with [Mo(CO)3C5H5]2. Syntheses and structures of the clusters C5H5(CO)2MoCo3(CO)6(μ-CO)3 and (C5H5)2(CO)3Mo2Co2(CO)4(μ-CO)3
Interaction of (mesitylene)Co4(CO)9 (I) with [Mo(CO)3Cp]2 (II) has been shown to result on a mixture of clusters Cp(CO)2MoCo3(CO)6(μ-CO)3 (III) and Cp2(CO)3Mo2Co2(CO)4(μ-CO)3 (IV). Complexes III and IV have also been obtained by an independent synthesis from Co2(CO)8 and II, the latter route is the most convenient and the simplest for the synthesis of III. X-ray diffraction studies on III and IV reveal

The reaction of Mn(2)(CO)(7)(mu-S(2)) with [CpNi(CO)](2) yielded the paramagnetic new compound Cp(2)Ni(2)Mn(CO)(3)(mu(3)-S)(2) (1) and a new hexanuclear metal product Cp(2)Ni(2)Mn(4)(CO)(14)(mu(6)-S(2))(mu(3)-S)(2) (2). Structurally, compound 1 contains two triply bridging sulfido ligands on opposite sides of an open Ni(2)Mn triangular cluster. EPR and temperature-dependent magnetic susceptibility
