hexamethylbenzene. Woth diphenylethyne, 3-hexyne and 4-octyne the formation of 1,3-cyclohexadiene complexes 3, 5 and 7 is observed as well as the cyclodimerization of the alkynes with formation of cyclobutadiene complexes 4, 6 and 8. The separation of corresponding cyclohexadiene and cyclobutadiene complexes is possible by high performance liquid chromatography, as is exemplified with the combination 3–4. Two-dimensional
