- W2030489045 abstract "Die Organocer(III)-Verbindung Na(THF)[(π-C5H5)3Ce(σ-C5H5)] (I) reagiert mit (C6H5CH2)3SnCl und (C6H5CH2)3TiCl im Sinne einer SN-Reaktion unter Abscheidung von NaCl und (C5H5)3Ce zu Tribenzylzinn- bzw. -titancyclopentadienyl (C6H5CH2)3MC5H5 [M = Sn, (II); Ti, (III)]. Eine eingehende Charakterisierung von II und III erfolgte durch Elementaranalysen, IR-Spektroskopie sowie durch 1H-, 13C- bzw. 119Sn-NMR-spektroskopische Untersuchungen. Diesbezügliche Resultate gestatten die Aussage, daßII bzw. III durch die Formeln (C6H5CH2)3Sn(σ-C5H5) und (C6H5CH2)3Ti(π-C5H5) zu beschreiben sind. About Tribenzyltin- and Tribenzyltitaniumcyclopentadienyl The organocerium(III) compound Na(THF)[(π-C5H5)3Ce(σ-C5H5)] (I) reacts with (C6H5CH2)3SnCl and (C6H5CH2)3TiCl after a SN-reaction under separation of Nacl and (C5H5)3Ce to tribenzyltin- resp.-titaniumcyclopentadienyl (C6H5CH2)3MC5H5 [M = Sn, (II); Ti, (III)]. A special characterization of II and III was carried out by their elementary analysis, I.R. spectroscopy and 1H, 13C, and 119Sn N.M.R. spectroscopy. These results allow the statement that II and III are better to be described by the formulae (C6H5CH2)3Sn(σ-C5H5) and (C6H5CH2)3Ti(π-C5H5), respectively." @default.
