Abstract
ihydro-1,2,3,4-tetramethyl-2-methylen-1H-imidazole (1) reacts with 1,3 ,4,5-tetramethyl-2-(methylthio)imidazolium iodide (4) in the presence of pyridine to give bis(1,3,4,5-tetra-methyl-2-imidazolyl)methylium io dide (5) which is also formed by the reaction of 4 and methyl lithium in the ratio 2:3. The X-ray structure of 5 is reported.
