Herein is described a fully regio- and stereoselective hydroelementation reaction of SF5-alkynes with N, O and S-nucleophiles and further functionalization of the corresponding Z-(hetero)vinyl-SF5 intermediates, a suitable platform to access α-SF5 ketones and esters, β-SF5 amines and alcohols under mild reaction conditions. Experimental and computational comparative studies between SF5- and CF3-alkynes have been performed to highlight and explain the difference of reactivity and selectivity observed between these two fluorinated motifs.
