✦ Synopsis

Oxime formation from 2-quinolinecarboxaldehyde occurs with rate-limiting carbinolamine dehydration under both acidic and neutral conditions. Carbinolamine dehydration occurs via a transition state bearing a single positive charge, similar to the corresponding reaction for 2-pyridinecarboxaldehyde and unlike the same reaction for 2-, 3 -, and 4-formyl-1 -methylpyridinium ions and for the conjugate acids of 3-and 4-pyridinecarboxaldehydes 0 1996 lohn W Iley G Sons.
