Silver lining: A catalytic enantioselective protonation of trimethylsilyl enolates uses a binap/silver(I) fluoride complex as a chiral catalyst in a mixture of dichloromethane and methanol (see scheme). Various ketones with tertiary asymmetric carbon centers at the α position can be prepared with high enantioselectivities.
