The reactions of oligofunctionalized 1,1-dinaphthylmethanes with primary amines and ammonia are described. In the reaction of amines with 2,2′,7,7′-tetrahydroxyand 2,2′-dihydroxy-1,1dinaphthylmethanes, the replacement of hydroxy groups by amino groups is accompanied by cleavage of С-С bonds and elimination of a methylene unit. The regiodirection of the process is determined by the number and the nature
描述了低聚官能化 1,1-二萘甲烷与伯胺和氨的反应。在胺与 2,2',7,7'-四羟基和 2,2'-二羟基-1,1二萘基甲烷的反应中,羟基被氨基取代伴随着 С-С 键的断裂和亚甲基的消除单元。该过程的区域方向由二萘甲烷核心中取代基的数量和性质决定。2,2',7,7'-四(三氟甲磺酰氧基)-1,1-二萘甲烷的催化胺化不伴随二萘甲烷核的破坏。反应选择性和产物结构取决于胺化试剂的性质。
