Allylsilanes in the synthesis of three to seven membered rings: the silylcuprate strategy
Beilstein Journal of Organic Chemistry, 2007 Addition of low order phenyldimethylsilylcyanocuprates to allenes followed by "in situ" reaction of the intermediate silylcuprate with electrophiles ("the silylcuprate strategy") provides new routes for the synthesis of functionalised allylsilanes, which

Borylation of Aryl Halides Induced by Visible Light Under Open‐To‐Air Environment
ChemSusChem, Volume 19, Issue 15, 14 August 2026.Borylation of aryl halides was successfully achieved by a sustainable protocol which involved a purely organic confined medium, visible light as energy source under an open‐to‐air environment. Experimental and computational investigations evidenced that the reaction occurred through the formation of a ground–state complex generated by hydrogen bonding.
