Darstellung und Eigenschaften von und Reaktionen mit metallhaltigen Heterocyclen, LXXXV. Konsekutive Insertions‐ und [2 + 2]‐Cycloadditions‐Reaktion von Hexafluor‐2‐butin mit einem (η²‐Thiophosphinito)cobalt‐Komplex

Abstract

Cycloaddition Reaction of Hexafluoro-2-butyne with an (qz-Thiophosphinito)cobalt ComplexInsertion of hexafluoro-2-butyne (2) into the Co-P bond of the results in the formation of the stable (q3-cyclobutenyl)cobalt (q2-thiosphosphinito)cobalt complex (OC)2Ph3PCo(qz-S PEt2) complex 3. According to an X-ray structural analysis 3 crys-(1) and subsequent 12 + 21 cycloaddition to a second alkyne 2 tallizes in the triclinic space group Pi with Z = 2.
