N2H4 as traceless mediator for homo- and cross- aryl coupling

Nature Communications, 2018
Synthesis of biaryls by coupling strategies is unavoidably accompanied by stoichiometric metal waste. Here, the authors report the homo- and cross-electrophile coupling by using hydrazine as metal surrogate, only liberating N2 and H2 as side products.

C-Metalated Nitriles:  Electrophile-Dependent Alkylations and Acylations

, 2016
Sequential carbonyl addition−conjugate addition of Grignard reagents to 3-oxocyclohex-1-ene-1-carbonitrile generates C-magnesiated nitriles whose alkylation stereoselectivities intimately depend on the nature of the electrophile.

Three-component N-alkenylation of azoles with alkynes and iodine(III) electrophile: synthesis of multisubstituted N-vinylazoles

Beilstein Journal of Organic Chemistry
A stereoselective N-alkenylation of azoles with alkynes and iodine(III) electrophile is reported. The reaction between various azoles and internal alkynes is mediated by benziodoxole triflate as the electrophile in a trans-fashion, affording azole ...
