The oxidative addition of Br 2 to the imidazoline‐2‐selone derivatives 1a − c has been studied by spectrophotometric and conductometric techniques. The experimental results clearly indicate that this reaction involves the dications 2a − c , containing an Se−Se bond, as intermediates in the formation of the hypervalent 10‐Se‐3 selenium compounds 3a − c containing the Br−Se−Br group. The crystal structure of 1,2‐bis(3‐methyl‐4‐imidazolin‐2‐ylium dibromoselenanide)ethane ( 3c ), a new stable hypervalent 10‐Se‐3 compound, is also reported.
