We have prepared four new oximes, lb-e, which conform to the general structure RCH, COCH= NOH where R= CH, S, CH, SO, CH, S02, and (CH3) 2Sf, respectively, and have the same E configuration as the parent 2-oxopropanal oxime la (R= H, MINA). The pK, values range from 6.54 (le) to 8.16 (lb), as compared with 8.30 for la. Rates of reaction (k,) with 4- nitrophenyl acetate indicate that the oximate anions have a much higher nucleophilicity ...
