摘要：

A combination of electrospray-ionization mass spectrometry and Mossbauer spectroscopy was used to investigate the species generated in situ in highly enantioselective Fe/NHC-catalyzed C-H alkylations. The findings indicate an organometallic iron(ii)-NHC species to be of key relevance in the asymmetric catalysis.
