5-Pentafluorobenzyl-3-o-tolylhydantoin (2) was synthesized for reducing this π-electron density, and NMR studies have shown that we have succeeded in changing the conformation of 2 into an extended system instead of the folded conformation for the non- fluorinated compound, 5-benzyl-3-o-tolylhydantoin (1). Molecular modeling has also confirmed the extended structure for 2. An approach has been found for possibly ...
