Imine types
WitrynaCamphor derivatives of the imine type (A L, OC 10 H 14 NY) were obtained by condensation of amines or hydrazines with camphor quinone, while from condensation of para or orto diamines, bi-camphor (B L, OC 10 H 14 N) 2 Z) or camphor phenazine (C L, NC 10 H 14 NY) type species were, respectively, obtained . Witryna30 sie 2024 · There are three kinds of dynamic equilibria of imine bonds (Fig. 5a) including imine hydrolysis/condensation, amine-imine transimination reation, and imine metathesis, which were widely exploited by researchers to prepare self-healing materials [55,56,57].
