摘要

Aromatic aldehydes1 and their oximes2 are important synthetic intermediates. In addition, p- aminobenzaldoximes show interesting chemical and biological activities. 3 It is known that only thermodynamically more stable E-oximes are formed by direct oximation of aromatic aldehydes," thus, the product of reaction of p-(N, N-dimethy1amino) benzaldehyde with hydroxylamineS is Ep-(N, N-dimethylamino) benzaldoxime6 and it is noteworthy that Z- ...
