The reaction of 1,3-diisopropylimidazolium chloride (3) with benzylpotassium in d5-bromobenzene generates the stable carbene 1,3-diisopropylimidazol-2-ylidene that is trapped by hafnium tetrachloride. A chloride anion is subsequently added to the Hf atom of the resulting intermediate to yield the salt [(1,3-diisopropylimidazol-2-ylidene)HfCl₅−][1,3-diisopropylimidazolium+] 6 that was characterized by an X-ray crystal structure analysis.
