Notes:
The oxidative addition of Br2 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.
