Dimethylaminoborane reacts with trimeric aminoboranes (RNH·BH2)3(R = Et and Pr) to give corresponding borazines: Me2N·BH2+⅓(RNH·BH2)3→ Me2NH,BH3+⅓(RNBH)3 Dimethylaminoborane also reacts with amine–boranes, RNH2,BH3(R = Me, Prn, and Pri). From reactions involving propyl- and isopropyl-amine–borane, stable 1,1-dimethyl-3,5-dialkylcyclotriborazanes, which are in effect cyclic mixed adducts, Me2N·BH2,2RNH·BH2
二甲基氨基硼烷与三聚氨基硼烷(RNH·BH 2)3(R = Et和Pr)反应生成相应的硼嗪:Me 2 N·BH 2 +⅓(RNH·BH 2)3 → Me 2 NH,BH 3 +⅓(RNBH )3二甲基氨基硼烷也与胺-硼烷RNH 2,BH 3(R = Me,Pr n和Pr i)反应。从涉及丙基和异丙基胺硼烷,稳定1,1-二甲基-3,5- dialkylcyclotriborazanes,其在效果环状混合加合物的反应中,Me 2 N·BH 2,2RNH·BH 2,已获得。
