4-哌啶-1-苯甲醛 | 4-(piperidin-1-yl)benzonitrile | 1204-85-9 | C12H14N2 | 186.257 |
The mercury-edta dehydrogenation of the 4′-aminosubstituted-acetophenones 1, 8a and 9a produced the ring cleavaged derivatives 7 ,11a and 12a, while the piperidine and its derivatives 10a - 10e gave rise to tetracyclic compounds 16a - 16e and to methylenedi-enamines 19a - 19d, the additionally C-1-fragment in 19a - 19d probably coming from mercury edta. With addition of m-nitrobenzaldehyde to the mercury-edta dehydrogenation of substituted phenylpiperidines another route only generated the di-enamines 22.
