A Kinetic Investigation of the Hydroxide-catalysed Detritiation of Various -15,16-Dihydrocyclopentaphenanthren-17-ones and Related Compounds

The hydroxide-catalysed detritiation rate constants from the C-16 position of a series of substituted -15,16-dihydrocyclopentaphenanthren-17-ones have been measured in a 90:10 (v/v) water-dioxane mixture at 25 deg C.The results show that methyl group substitution brings with it, in addition to the costumary deactivating effect, a marked acceleration in rate, which probably has its origin in steric strain considerations.Similar studies involving the analogous position in a number of related ketones (benzindanone, indanone, and cyclopentanone) show that the rates are not simply a function of the number of additional benzene rings but depend on their position relative to the cyclopentanone system.
