Strong distortions in hexacarbonyldicobalt complexes by push–pull effects

Push–pull substituted alkynes with a thioether moiety in the α position and a sulfoxide or a sulfone moiety in the α′ position are reacted with octacarbonyldicobalt to create highly distorted hexacarbonyldicobalt complexes.

Theoretical considerations lead to the hitherto most distorted hexacarbonyldicobalt complexes that are obtained by reaction of push-pull substituted alkynes with Co2(CO)8.Figure optionsDownload as PowerPoint slide
