tetramethyl-2-octene (4), prepared via prenyl chloride addition to 2,3,3-trimethyl-1 -butene, at room temperature undergoes a zinc chloride/hydrogen chloride-catalysed cyclocondensation to yield 1,2,3,3,6,6-hexamethyl-l-cyclohexene (1). The reaction mechanism is elucidated by isolation of intermedia
