With hydrazines 1,2,4-triazolium salts (3, 4) were formed. 1,3-Dimethylurea, respectively 1,3-dimethylthiourea or ethyl allophanate, reacted with 1 to afford 2-oxo- or 2-thioxo-1,3,5-triazinium salts (5–7). With diphenylmethaneimines imino substituted 2-azoniaallene salts 8 were produced. From chloroacetonitrile dichloropyrimidines 9, and from the tricyanomethyl anion a hexatriene 10 and a triazine 11 could be prepared. The 1,5-dichloro substituted 2-azoniaallene salts 12 reacted as bifunctional electrophiles with nucleophiles such as benzophenone hydrazone or anilines, to furnish 1,3,5-triazinium salts 14. Against benzohydrazide the allene 12j behaved as trivalent electrophile giving the bicyclic 1,3,5-oxadiazinium salt 13j, the constitution of which has been secured by a crystal structural analysis. The vinyl-2-azoniaallene salt 1i cyclized on heating to the 1,3-thiazinium salts 16, 17. From 17 the triazinium salts 18 were prepared with alcohols.</dcterms:abstract> <dcterms:bibliographicCitation>Journal für Praktische Chemie - Chemiker-Zeitung ; 337 (1995), 1. - S. 274-282</dcterms:bibliographicCitation> <dc:contributor>Hamed, A.</dc:contributor> <dc:date rdf:datatype="">2013-06-25T13:25:43Z</dc:date> <dcterms:issued>1995</dcterms:issued> <dc:contributor>Jochims, Johannes C.</dc:contributor> <dc:contributor>Sedeak, Mohamed</dc:contributor> <dc:contributor>Stumpf, Rüdiger</dc:contributor> <dc:creator>Ismail, Abd El-hamid</dc:creator> <dcterms:available rdf:datatype="">2013-06-25T13:25:43Z</dcterms:available> <dcterms:rights rdf:resource=""/> <dcterms:title>Some reactions of 1,3-Dichloro-2-azoniaallene Salts with heteronucleophiles</dcterms:title> <dc:creator>Jochims, Johannes C.</dc:creator> <dc:creator>Stumpf, Rüdiger</dc:creator> <dc:language>eng</dc:language> <dc:creator>Sedeak, Mohamed</dc:creator> <bibo:uri rdf:resource=""/> <dc:creator>Fischer, Helmut</dc:creator> </rdf:Description> </rdf:RDF>
