a, Composition of solutions initially containing a 1:1 mixture of 1a and 1b as starting materials at 19 °C in HFIP and iPrOH. After 180 min, formation of 1c and monoselanes is observed through Se–Se and Se–C σ-bond interchange, respectively. Numbers in the pie charts refer to relative amounts of 1a (dark blue), 1b (medium blue) and 1c (light blue) in solution. b, Composition of solutions containing 2a–1d as the starting material at 19 °C in HFIP and iPrOH after 180 min.
