When elemental selenium was added to a strongly basic amine, 1,8‐diazabicyclo[5.4.0]undec‐7‐ene (DBU) or 1,5‐diazabicyclo[4.3.0]non‐5‐ene (DBN), the selenium started to dissolve and the solution turned dark brown. We investigated the chemical reaction of this selenium dissolution process by electrospray ionization mass spectrometry (ESI‐MS). The study reveals for the first time that cleavage of SeSe bonds by the amine initiates the reaction to form molecular Se 2 , which then abstracts hydrogen from the amine molecule. ESI‐MS with the use of a nanospray technique was shown to be a useful tool for studying the dissolution of elements in strongly basic or acidic solvents. Copyright © 2004 John Wiley & Sons, Ltd.
