Stepwise addition of difluorocarbene to a transition metal centre†
Abstract
The Ruppert–Prakash reagent (Me3SiCF3) is used to introduce difluorocarbene (CF2) and tetrafluoroethylene (TFE) ligands to cobalt(I) metal centres, whereby the TFE ligand is generated via [2+1] cycloaddition between [Co]CF2 and CF2.
