 In 1830, Zeise attempted to react platinum chloride with ethanol, leading to a series of platinum-based organometallic compounds.One of these compounds, originally referred to by Zeise himself as “"sal kalicoplatinicus inflammabilis"”, was subsequently named after him according to the tradition of the day – it is still called Zeise's salt.Zeise's claim that the newly discovered salt contained ethylene was received with distrust by Justus von Liebig, whose understandable attacks on Zeise were quite unjustified.
