After initial loss of a neutral (CH3)Zn(O-i-C3H7) unit to afford [(CH3)2Zn3(O-i-C3H7)3]+, hydrogen migration leads to the expulsion of neutral acetone concomitant with [(CH3)2Zn3(O-i-C3H7)2(H)]+ as ionic fragment. Unimolecular dissociation of the latter gives rise to [(CH3)2Zn2(O-i-C3H7)]+ and neutral HZn(O-i-C3H7). As demonstrated by collisional ionization of the neutral product, in the fragmentation of the dinuclear cluster [(CH3)2Zn2(O-i-C3H7)]+ neutral CH3ZnH is formed, rather than the more stable fragments Zn þ CH4. From the resulting mononuclear species CH3Zn(OC(CH3)2)+ acetone is eliminated to afford CH3Zn+ as a quasi-terminal fragment ion.</dcterms:abstract> <dc:creator>Driess, Matthias</dc:creator> <dc:creator>Schwarz, Helmut</dc:creator> <dc:contributor>Schröder, Detlef</dc:contributor> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-24T18:15:07Z</dc:date> <dc:contributor>Polarz, Sebastian</dc:contributor> <dcterms:bibliographicCitation>First publ. in: Physical Chemistry, Chemical Physics 7 (2005), pp. 1049-1053</dcterms:bibliographicCitation> <dcterms:rights rdf:resource="https://creativecommons.org/licenses/by-nc-nd/2.0/legalcode"/> <dcterms:issued>2005</dcterms:issued> <dc:language>eng</dc:language> <dc:rights>deposit-license</dc:rights> <bibo:uri rdf:resource="http://kops.uni-konstanz.de/handle/123456789/9889"/> <dc:creator>Polarz, Sebastian</dc:creator> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-24T18:15:07Z</dcterms:available> <dc:creator>Schröder, Detlef</dc:creator> <dcterms:title>Consecutive fragmentations of the cubane-like zinc cluster [CH3Zn(O-i-C3H7)]4 upon electron ionization</dcterms:title> </rdf:Description> </rdf:RDF>
