Fe³⁺-mediated selective 1,2-Se (S) bifunctionalization of olefin

A one-pot, four-component reaction for simultaneously constructing C-Se, C-S, and C-N bonds <i>via</i> iron-mediated olefin 1,2-bifunctionalization was described. β-Selenylethyl dithiocarbamates were obtained highly efficiently with a wide substrate scope and remarkable regioselectivity. Notably, non-activated olefins exhibit higher reactivity in this reaction system, achieving yields of up to 99%.
