- W1986930939 abstract "Die Deprotonierung von tautomeriefähigen N-(1-Phenylalkyliden)methylaminen 5 kann nur dann an der N-Methylgruppe erfolgen, wenn Phenylkern und C N-Doppelbindung koplanar angeordnet sind. Dies ist nur bei E-Konfiguration möglich. Allerdings führt auch dann die in allen anderen Fällen beobachtete Abspaltung des α-Wasserstoffs gewöhnlich zum stabileren Anion. Eine Ausnahme bildet das E-Isomere des N-(2-Methyl-1-phenylpropyliden)methylamins (5c). Deprotonation of Tautomerizable N-(1-Phenylalkylidene)methylamines. Competitive Formation of 1-Azaallyl- and 2-Azaallyl Anions Deprotonation of tautomerizable N-(1-phenylalkylidene)methylamines 5 can only occur at the N-methyl group if phenyl nucleus and C N-double bond are coplanar. This is possible in the E-configuration only. But even in this case the normally observed abstraction of α-hydrogen produces the more stable anion. An exception is the E-isomer of N-(2-methyl-1-phenylpropylidene)-methylamine (5c)." @default.
