Synthese und reaktionen von pentamethylcyclopentadienylzinn-verbindungen

Synthesis, Characterization, and Stoichiometric U–O Bond Scission in Uranyl Species Supported by Pyridine(diimine) Ligand Radicals

“…The solvent of the mother liquor was evaporated to afford a slurry from which (C 5 Me 5 ) 2 was identified by 1 H NMR spectroscopy. 24,25 Synthesis of [(CH 3 ) 3 SiO]UI 3 (THF) 3 (6-THF) from 3. A 20 mL scintillation vial was charged with Cp*UO 2 ( Mes PDI Me ) (3) (0.138 g, 0.172 mmol) and 5 mL of toluene.…”

Pentamethylcyclopentadienylselenium derivatives VI: Synthesis and characterisation of ferrocenyl(pentamethylcyclopentadienyl)selenium

“…Two bands were collected. The first of these contained C 10 Me 10 [16]. The second green band yielded [W 2 (lSeFc) 2 (CO) 8 ] (5) in approximately 60% yield.…”

“…The products were passed through a short silica column using this solvent as eluent under an inert atmosphere. A yellow solution containing C 5 Me 10 [16] was obtained first; a subsequent green band afforded 5, identified by comparison of its NMR, IR and mass spectra with those of an authentic sample [17]. Yield: 85 mg (61%).…”

Tetrakis-pentamethylcyclopentadienyl-cyclotetrastiban (PcpSb)4 : Synthese, Molekül-und Kristallstruktur / Tetrakis-pentamethylcyclopentadienyl-cyclotetrastibane (PcpSb)4 : Synthesis, Molecular and Crystal Structure

“…Jutzi et al [17] haben reduktive Eliminierung aus Pentamethylcyclopentadienyl-Zinndihalogeniden beobachtet und dabei erstmals das dimere (Pcp) 2 isoliert. Wir haben bei unseren Reaktionen ebenfalls (Pcp) 2 erhalten und berichten über dessen Molekül-und Kristallstruktur, Dekamethyldicyclopentadien, an anderer Stelle [18].…”
