Synthese und optische Eigenschaften endstandig substituierter konjugierter Polyene mit Bicyclo[2.2.2]octan als Spacer
The conjugated polyenes 10, 11, and 17 respectively, with 9anthryland 2-tetraphenylporphyrinyl (TPP) terminal groups and a bicyclooctane unit incorporated into the polyene chain were synthesized by Wittig olefinations. In all cases it was possible to obtain the all-(4 compounds from the (Q/(Z)-isomeric mixtures by chromatographic purification and several recrystallizations. From the UV/Vis spec...
متن کاملSynthesis and structures of doubly-bridged dicyclopentadienyl dinuclear rhenium complexes, and their photochemical reactions with aromatic halides in benzene.
Reaction of the doubly-bridged biscyclopentadienes (C5H4(EMe2))(C5H4(SiMe2)) (E = Si(1a), or C(1b)) with Re2(CO)10 in refluxing mesitylene gave the corresponding dirhenium carbonyl complexes [(η(5)-C5H3)2(EMe2)(SiMe2)][Re(CO)3]2 (trans-2a,b and cis-2a,b), and the desilylated products [(η(5)-C5H4)2(EMe2)][Re(CO)3]2 (3a,b). Photolysis of trans-2a,b with a series of aryl halides in benzene results...
متن کاملReactivity of vinyl and alkynyl zirconium complexes with the di-ansa-[1,1%,2,2%-bis(dimethylsilanediyl) dicyclopentadienyl] ligand
Vinylation of the chloro–ethyl and dichloro zirconium complexes [Zr(CpSi2Cp)ClX] (CpSi2Cp=1,1%,2,2%-(SiMe2)2(h-C5H3)2; X=Et, Cl) with one or two equivalents of Mg(CH CH2)Cl gave the new zirconacyclopentane [Zr(CpSi2Cp){hCH2 (CH2)2 CH2}] and (h-butadiene)zirconium [Zr(CpSi2Cp){h-(butadiene)}] complexes, respectively. Addition of a toluene solution of PhC CPh to the zirconacyclopentane compound a...
متن کاملComplexes of a gallium heterocycle with transition metal dicyclopentadienyl and cyclopentadienylcarbonyl fragments, and with a dialkylmanganese compound.
The reactivity of several transition metal half sandwich complexes towards an anionic gallium(I) heterocyclic complex, [K(tmeda)][Ga{[N(Ar)C(H)]2}](Ar = C6H3Pri2-2,6), has been investigated. This has led to the anionic half sandwich complexes, [K(tmeda)][(C5H4R)M(CO)n[Ga{[N(Ar)C(H)]2}]](M = V, R = H, n= 3; M = Mn, R = Me, n= 2; M = Co, R = H, n= 1), which crystallographic studies show to form d...
