Surprisingly, their cyclohexanes boiled higher by 10 °C than either hexahydrobenzene or hexanaphtene, but this riddle was solved in 1895 by Markovnikov, N.M. Kishner, and Nikolay Zelinsky when they reassigned "hexahydrobenzene" and "hexanaphtene" as methylcyclopentane, the result of an unexpected rearrangement reaction.
Surprendentemente, os seus ciclohexanos fervían a 10 °C máis que o hexahidrobenceno e o hexanafteno, pero este complicado enguedello solucionárono en 1895 Markovnikov, N.M. Kishner, e Nikolay Zelinsky cando reasignaron o "hexahidrobenceno" e o "hexanafteno" como metilciclopentano, resultado dunha inesperada reacción de rearranxo.
