Subsequent reaction of 2a,b with PiPr3 in excess gives trans-[Br(PiPr3)2Pd−CCC(=O)NR2] (5a,b). The analogous reaction of 2b with P(C6H4OMe-4)3 gives trans-[Br(P{C6H4OMe-4}3)2Pd−CCC(=O)NR2] (7b), and that of 2a with trifluoroacetate gives trans-[(F3CCOO)(PPh3)2Pd−CCC(=O)NMe2] (9a). Methylation of 2a,b, 7b, and 9a with either MeOTf or [Me3O]BF4 and ethylation of 2a,b with [Et3O]BF4 yield the first cationic allenylidene complexes of palladium, trans-[R*(PR′3)2Pd−CCC(OMe)NR2]+X− (R* = Br, CF3COO; R′ = Ph, C6H4OMe-4, iPr; X = OTf, BF4).</dcterms:abstract> <dc:creator>Fischer, Helmut</dc:creator> <dc:creator>Szesni, Normen</dc:creator> <dc:contributor>Szesni, Normen</dc:contributor> <dcterms:issued>2009</dcterms:issued> <dc:language>eng</dc:language> <dc:contributor>Fischer, Helmut</dc:contributor> <dc:creator>Weibert, Bernhard</dc:creator> <dc:creator>Kessler, Florian</dc:creator> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-06-30T22:25:04Z</dcterms:available> <dc:rights>deposit-license</dc:rights> <dc:creator>Põhako, Kaija</dc:creator> <dc:contributor>Weibert, Bernhard</dc:contributor> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-24T18:15:50Z</dc:date> <dcterms:bibliographicCitation>First publ. in: Organometallics 28 (2009), 1, pp. 348-354</dcterms:bibliographicCitation> <dcterms:rights rdf:resource="http://nbn-resolving.org/urn:nbn:de:bsz:352-20140905103416863-3868037-7"/> </rdf:Description> </rdf:RDF>
