Synthesis of S - 2-Chlorophenyl mesityl methanol

To a mixture of Rh((S,S)-Fc-tfb )[ -(C5H5)BPh3] (1.75 pmol, 2.5 pmol of Rh) is added 2-ClCgH, B(OH)2 (0.5 mmol), powdered KOH (0.38 mmol), and t-butyl alcohol (1 ml) and stirred for 2 min at room temperature [11]. Mesitylaldehyde (0.25mmol) is added to the mixture and it is stirred at 30°C and monitored by TLC. The mixture is diluted with hexane and it is passed through a short column of silica gel with Et20 as eluent. After
