A free-radical-promoted stereospecific denitro silylation of β-nitroalkenes with silanes

A Cu-catalyzed stereospecific denitro silylation of β-nitroalkenes with silanes for the synthesis of vinylsilanes using DTBP as the oxidant was developed. This method presented an inexpensive and non-toxic catalytic system with an appropriate substrate scope. This approach is (E)-specific and produced an important class of vinylsilanes in good yields.
