DOI: 10.1021/acs.macromol.8b02654
Abstract: Secondary amine-derived aminal bonds represent an attractive class of dynamic covalent bonds that undergo rapid exchange reaction under mild conditions without the need of exogenous catalysts. The aminal bond exchange occurs by a dissociative transamination… read more here.
