extreme case, there was a 40-fold selectivity reversal. Lithiumborohydride showed no such change in selectivity and favored acetyl reduction in both solvents. Salt and cosolvent effects indicate that hydrophobic packing is involved in the reaction of hydrophobic reagents with the aryl ketones. Some special interaction of the pentafluorophenyl group with aryl rings was also detected.
