DOI: 10.1021/acs.orglett.8b00496
Abstract: Vinylsilanes were directly prepared from the corresponding vinyl triflates under magnesium-promoted reductive conditions in THF with no transition metal catalyst, and gem-bis-silylated compounds were obtained in NMP. Investigation of the redox potential of starting materials… read more here.

DOI: 10.1039/d0nj02612c
Abstract: The hydroboration of alkynes with pinacolborane (HBpin) under catalyst- and solvent-free conditions was demonstrated. Various alkynes were smoothly converted into alkenyl boronate esters in good to excellent yields at 110 °C. The gram-scale hydroboration of… read more here.
