Visible-light promoted atom transfer radical addition-elimination (ATRE) reaction for the synthesis of fluoroalkylated alkenes using DMA as electron-donor [PDF]
, 2020 Here, we describe a mild, catalyst-free and operationally-simple strategy for the direct fluoroalkylation of olefins driven by the photochemical activity of an electron donor-acceptor (EDA) complex between DMA and fluoroalkyl iodides.

2-Aminoethanaminium iodide [PDF]
Acta Crystallographica Section E Structure Reports Online, 2012 The title salt, [NH3CH2CH2NH2]+·I−, has an array structure based on strong intermolecular N—H...N hydrogen bonding formed between the ammonium and amine groups of adjacent cations. This interaction gives a helical chain of cations that runs parallel to the b axis.

Nickel-catalyzed carbonylative synthesis of dihydrobenzofurans
Catalysis Communications, 2021 A nickel-catalyzed carbonylative synthesis of dihydrobenzofurans has been developed. With Mo(CO)6 as the CO source and manganese metal as the reductant, alkyl halides were reacted with aryl iodides to give the desired products in moderate to good yields.
