Canyou kill two catalysts with one chloride? Thiourea/urea catalysts are sensitive to inhibition by chloride salts, but here we find that they appear to be too sensitive. Are two catalysts inhibited by a single chloride ion, or are there two catalysts involved in the reaction? Our kinetic detective story suggests the latter!
