Abstract

Functionalised pyridinium and ammonium ionic liquids bearing a Michael acceptor are shown to scavenge H2S gas and various thiols, in most cases, without the aid of any added bases. Utilising the effective non-volatility of ionic liquids and ‘tagging’ malodourous substances to an ionic matrix renders them odourless.
