Several 9-substituted 9-(2-methylthiophenyl) fluorene derivatives and their oxidation products, 9-substituted 9-(2-methylsulfinylphenyl) fluorene derivatives were prepared. Each equilibrium constant was investigated and the conformational equilibria ap\ rightleftarrowssp of these compounds were discussed on the basis of nonbonding intramolecular interactions (attraction or repulsion) between 2-substituents in phenyl moieties (methylthio or ...
