Summary:Aminborany(3), kde aminovou skupinou je dimethylaminov skupina, morfolinyl, nebo pyridyl, se p°ipravuj reakc hydrochlorid odpov daj c ch amin s tetrahydroboritanem sodn²m v dimethoxyethanu, kter se prov d v p°ebytku tetrahydroboritanu sodn ho, ke kter mu se postupn p°id v hydrochlorid aminu do kone n ho mol rn ho pom ru tetrahydroboritanu sodn ho a hydrochloridu aminu 1 a 1,1:1.\ In the present invention, there are disclosed amino boranes(3), in which the amino group is represented by dimethyl amino group, morpholinyl, or pyridyl. These compounds are prepared by reacting hydrochlorides of corresponding amines with sodium tetrahydroborate in dimethoxyethane, whereby the reaction is carried out in excess of the sodium tetrahydroborate to which successively amine hydrochloride is added until the final molar ratio of the sodium tetrahydroborate to amine hydrochloride is 1 to 1.1:1.
