Notes:
The 13C NMR spectra of 2-arylspiro[cyclopropane-1,9′-thioxanthene S,S-dioxides], 1-5, and 2′-aryl-spiro[10,11-dihydro-5H-dibenzo[a,d]cycloheptene-5,1′-cycyclopropanes], 6-9, are described, and the effects of substituents are discussed. The relationship between the 13C shifts and the Hammett σ constants of substituents on the phenyl ring is not linear for 1-5. For 6-9 the chemical shifts of the cyclopropane carbons (C-2′ and C-3′) correlate reasonably well with electron density.
