Abstract: Abstract The development of a visible light-mediated atom transfer radical addition (ATRA) of perfluoroalkyl iodides to potassium 1-penten-5-yl-, vinyl- and allyltrifluoroborates using the reductive quenching of [Ru(bpy) 3 ]Cl 2 or [Ru(bpy) 3 ](PF 6… read more here.

Abstract: A nickel catalyst for the allylboration of aldehydes is reported, facilitating the preparation of homoallylic alcohols in high diastereoselectivity. The observed diastereoselectivities and NMR experiments suggest that allylation occurs through a well-defined six-membered transition state,… read more here.
