Takuji Hatakeyama,Yu Ichi Fujiwara,Yoshihiro Okada,Takuma Itoh,Toru Hashimoto,Shintaro Kawamura,Kazuki Ogata,Hikaru Takaya,Masaharu Nakamura +8 more
TL;DR: An iron(II) chloride complex possessing a sterically demanding ortho-phenylene-tethered bisphosphine ligand showed a high catalytic activity in the Kumada-Tamao-Corriu coupling of nonactivated alkyl... as mentioned in this paper.

Diastereoselective Carbometalation of Oxa- and Azabicyclic Alkenes under Iron Catalysis.
TL;DR: In the presence of catalytic amounts of FeCl3 and diphosphine ligand PDP, oxa- or aza-bridged dihydronaphthalenes, oxabicycle (XIV) or trioxasilatricycle (XVI) are metalated by diarylzinc compounds, which are prepared from ZnCl2 and arylmagnesium bromides prior the reaction as discussed by the authors.

TL;DR: In this article, the first enantioselective carbometalation reaction of azabicycloalkenes has been achieved by iron catalysis to in situ form optically active organozinc intermediates, which are amenable to further synthetic elaborations.
