TL;DR: In this paper, the structural aspects for the complexation of xanthone and fluorenone to α- as well as β-cyclodextrins (CDxs) were explored by combining absorption, fluorescence, and induced circular dichroism studies with theoretical calculations of the optimized structures for the ketone−CDx complexes and their predicted ICD spectra.
Abstract: The structural aspects for the complexation of xanthone and fluorenone to α- as well as β-cyclodextrins (CDxs) were explored by combining absorption, fluorescence, and induced circular dichroism studies with theoretical calculations of the optimized structures for the ketone−CDx complexes and their predicted ICD spectra. Detailed information on the similarities and differences for the complexes of these ketones with CDxs was obtained. For both CDxs, the ketones are bound to the rim of the cavity, and deeper penetration is observed for the complexes with β-CDx. In addition, a 1:2 complex involving α-CDx was only observed in the case of fluorenone. Although the two ketones have similar structures, their molecular recognition properties and the resulting structures of the CDx complexes show distinct differences.

TL;DR: The isotope effect for this cyclization was found to be 1.12 and 1.32 for k/sub H/k/sub D/ was found for this reaction as discussed by the authors.
Abstract: S>2-(2-Deuteriophenyll-benzaldehyde (I) has been allowed to react with di-t-butyl peroxide to give fluorenone. An isotope effect, k/sub H/k/sub D/, of 1.38 was observed for this reaction. 2-(2-Deuteriophenyll-benzoyl peroxide (In has been cyclized by heating to give the lactone of 2carboxy-2'-hydroxybiphenyl (IIIa,b). An isotope effect of 1.32 for k/sub H/k/sub D/ was found for this reaction. Irradiation of 2-(2-deuteriophenyll-phenyldiazomethane (VI) gave fluorene. The isotope effect for this cyclization was found to be 1.12. (auth)
