hindered endo-aryl phosphines. These phosphines function as efficient catalysts for the kineticresolutions of aryl alkyl carbinols by benzoylation (16, 21, 22) or iso-butyroylation in the case of the less hindered aryl alkyl carbinol substrates. With o-substituted aryl alkyl carbinols, the enantioselectivities exceed 100, and s = 380 +/- 10 has been demonstrated in the case of methyl mesityl carbinol
