Depriving a selenenic acid (RCH 2 SeOH) of water results in its transformation into a selenoaldehyde (RCHSe). In their Communication on page 901 ff., K. Goto and co‐workers investigate the β‐dehydration reaction to form a CSe bond. The selenenic acid self‐catalyzes this transformation through a dehydrative condensation (to form a selenoseleninate intermediate) and a subsequent β‐elimination. A dendrimer‐type cradle protects both the selenenic acid and the selenoaldehyde, which are otherwise evanescent.
