Triethoxysilane-Catalyzed Sequential Regioselective Hydroboration of Terminal Alkynes: Sustainable Access to E-Alkenylboronate and Alkyl Gem-Diboronate Esters [PDF]
The commercial reagent, HSi(OEt)3, was an efficient catalyst for the synthesis of E-alkenylboronate esters and alkyl gem-diboronate esters by single or double hydroboration of terminal alkynes with HBPin (pinacolborane).
