and methacrylamides. Herein we provide a facile multi-gram high yield synthesis of these monomeric precursors to stimuli-responsive polymers by the addition of acrylamides and methacrylamides onto in situ generated or freshly isolated methylene Schiff base (iminium) salts. The X-ray crystal structure of the hydrated iminium salt, 1-(hydroxymethyl)azocan-1-ium chloride and monomer·HCl salt (N-[(azoca
传统的热曼尼希反应不适用于制备可聚合的N-亚甲基氨基取代的丙烯酰胺和甲基丙烯酰胺。本文中,通过将丙烯酰胺和甲基丙烯酰胺添加到原位生成的或新鲜分离的亚甲基席夫碱(亚胺)盐上,我们提供了这些单体前体对刺激响应性聚合物的简便的多克高收率合成。描述了水合亚胺盐,1-(羟甲基)偶氮坎-1-鎓氯化物和单体·HCl盐(N -[((偶氮烷-1-基)甲基]丙-2-烯酰胺盐酸盐)的X射线晶体结构。。
