New areneacetylenedicarbonylchromium chelate complexes containing the terminal acetylene fragment in the side chain of the arene ligand were synthesized. The rearrangement of these chelates to the previously unknown areneallenedicarbonylchromium chelate complexes was found and studied. It was demonstrated that this rearrangement is in principle reversible. For areneallenedicarbonylchromium chelates
合成了在芳烃配体侧链中含有末端乙炔片段的新型芳烃乙炔二羰基铬螯合物。发现并研究了这些螯合物与以前未知的芳烃二羰基铬螯合物的重排。已证明这种重排原则上是可逆的。对于芳烃二羰基铬螯合物,发现了金属重排的一个新例子,并且首次检测到两种异构体,即在丙二烯配体的取代或未取代双键上的配位。质子和亲核试剂在配位三键处的偶合加成提供了相应的芳烃烯烃螯合物。
