X-ray crystallography data, DFT calculations and cyclic voltammograms in synergy shed light on the mer4fac isomerization process of Cr carbenes of the type [(CO)3(dppe)Cr]C(X)R] with R ¼ 2-thienyl or 2-furyl and X ¼ OEt ...

The activation of a section, or of all the carbons of thiophene by bromine in lithium–halogen exchange reactions, was implemented in a step-wise manner to facilitate the preparation of novel multiple Fischer carbene-bearing ...
