sp-9-(o-tert-Butylphenyl)-3-(methylthio)fluorene: a Major Rearrangement Product from the Facile Uncatalyzed Decomposition of ap-9-(o-tert-Butylphenyl)-9-(methylthio)fluorene

On short-term heating, highly strained ap-9-(o-tert-butylphenyl)-9- (methylthio)fluorene underwent facile cleavage of the C-S bond. Migration of the methylthio group produced sp-9-(o-tert-butylphenyl)- 3-(methylthio)fluorene (C₂₄H₂₄S) as the major product, whose geometrical parameters show a great reduction in distortion and strain compared to those of the ap substrate.
