Catalytic coupling of N-benzylic sulfonamides with silylated nucleophiles at room temperature.
In the presence of 2-10 mol% of Tf(2)NH, a range of N-benzylic sulfonamides smoothly react with allylic, propargylic, benzylic, or hydrido silanes at room temperature via sp(3) carbon-nitrogen bond cleavage to afford structurally diverse products in moderate to excellent yields and with high chemo- and regioselectivity.
