An alkene-alkyne-silylene [2 + 2 + 1] cycloaddition takes place in the rhodium-catalyzed reaction of 1,6-enynes with borylsilanes bearing an alkoxy group on the silicon atoms, which react as synthetic equivalents of silylene. The reaction proceeds efficiently in 1,2-dichloroethane at 80-110 °C in the presence of a rhodium catalyst bearing bis(diphenylphosphino)methane (DPPM) as a ligand to afford 1-silacyclopent-2-enes in good to high yields.
Lewis acidic FeCl3 promoted 2-aza-Cope rearrangement to afford α-substituted homoallylamines in dimethyl carbonate

, p. 18013 - 18017 (2019/06/24)
The iron(iii)-catalyzed efficient strategy for the synthesis of α-substituted homoallylamines was accomplished via a cationic 2-aza-Cope rearrangement of aldimines, generated in situ by condensation of commercially available aldehydes and easily synthesizable 1,1-diphenylhomoallylamines. This reaction features a broad substrate scope with high yields and is conducted in an eco-friendly solvent, i.e. dimethyl carbonate.

Iron-catalyzed oxidative C - H/C - H cross-coupling: An efficient route to α-quaternary α-amino acid derivatives
Li, Kaizhi,Tan, Guangying,Huang, Jingsheng,Song, Feijie,You, Jingsong
supporting information, p. 12942 - 12945 (2014/01/06)
Fully loaded: A coordinating activation strategy has been developed to furnish α-quaternary α-amino acids through the iron(III)-catalyzed oxidative functionalization of α-C(sp3) - H bonds of α-tertiary α-amino acid esters. The reaction exhibits a broad substrate scope for both α-amino acids and nucleophiles (Nu) as well as good functional-group tolerance (see scheme, DTBP=di-tert-butyl peroxide, DCE=1,2-dichloroethane).

C-C bond-forming reactions via Pd-mediated decarboxylative α-lmino anion generation
Yeagley, Andrew A.,Chruma, Jason J.
, p. 2879 - 2882 (2008/02/07)
α-lmino anions are generated under neutral reaction conditions via a Pd-mediated decarboxylation of allyl diphenylglycinate imines with concomitant formation of a π-allylpalladium species. The resulting delocalized anion can attack the π-allyl-Pd(ll) spec
