Abstract

Abstract Die Äthinylketon-Komplexe 3 lassen sich aus den Äthinylketonen 1 und Tris (triphenylphosphin) rhodium (I)-chlorid (2) unter schonenden Bedingungen in Substanz gewinnen. Schärfere Bedingungen (siedendes Xylol) führen unter Decarbonylierung unmittelbar zu den entsprechenden konjugierten Diinen 6, Bis (triphenylphosphin) rhodium (I)-carbonyl-chlorid (7) und Triphenylphosphin (4). Auf Grund dieser Befunde wird ein ...
