The mechanism of the bicyclization reaction of a series of terphenyl‐bisfluorenols into dispiro[fluorene‐9,6′‐indeno[1,2‐b]fluorene‐12′,9′′‐fluorene] and dispiro[fluorene‐9,6′‐indeno[2,1‐a]fluorene‐12′,9′′‐fluorene] is reported. Through a combined experimental and theoretical study, the different parameters that drive the regioselectivity of this cyclization reaction have been studied and are presented
