“…Application of Hoffmann's isolobal relationship [31] resulted in the discovery of a new approach to the synthesis of heterometallic vinylidene clusters [2,32], namely consecutive assembling of the MM M framework with the use of the metalla-allene M C C and methylenedimetallacyclopropane MM (-C C) systems as "building blocks". As a result, trimetal 3 -vinylidene complexes with triangular MnFePt frameworks and MnFePt chain [32,33] and a series of 4 -vinylidene PtFe 3 [33][34][35] and PdFe 3 [29,[36][37][38] clusters were synthesized.…”

“…Ранее на основе реакций биядерных комплексов Cp(CO) 6 (L), содержа-щих только терминальные фосфорсодержащие и карбонильные лиганды при атоме платины [25,26]. Однако реакции биядерных винилиденовых MnPt комплексов, содержащих хелатные дифосфиновые лиганды с нонакарбонилом дижелеза приводили к отщеплению циклопентади-енилатрикарбонил марганца и образованию продуктов переметаллирования исходных соеди-нений (рис.…”

“…Ранее для трехъядерного кластера типа CpMnFePt(μ 3 -C=CHPh)(CO) 6 [P(OPr i ) 3 ] была по-казана возможность замещения карбонильного лиганда при атоме платины на триизопро-пилфосфитный лиганд с образованием пентакарбонильного кластера CpMnFePt(μ 3 -C=CHPh) (CO) 5 [P(OPr i ) 3 ] 2 [25]. Однако возможность замещения как фосфинового, так и карбонильного лагандов при платине в CpMnFePt(μ 3 -C=CHPh)(CO) 6 Cp(CO) 2 Re(µ-C=CHPh)Pt(dppe) (7) и Cp(CO) 2 Re(µ-C=CHPh)Pt(dppp) (8) с нонакарбонилом дижелеза.…”

“…We have shown previously l'z that reactions of .u-vinylidene complexes Cp(CO);MnPt(I~-C=CHPh)I-,2 with iron nonacarbonyl can occur via two alternative routes depending on the nature of ligands L. When L = PPh3, the addition of the [Fe(CO)4] to vinylidene results in the formation of the trinuclear MnFePt la3-vinylidene cluster, l When L2 = Ph2PCH~_CH2PPh2 (dppe), the [Mn(CO)2CP] fragment is replaced by {Fe(CO)4] to form the tetranuclear PtFe3-~4-vinylidene cluster, z In continuation of the systematic studies in this area, we synthesized the first ~-vinylidene complex with the Mn--Pd bond (2) from Cp(CO)2Mn=C=CHPh (1) and Pd(PPh3) 4. (1,1-Dicarbonyl)(l-qS-cyclopentadienyl) ( 1,2-ls-phenylvinylidene) [2-rl2-bis(diphenylphosphino)ethane]manganesepalladium (3) was obtained by the replacement of the PPh 3 ligand by dppe.…”
