Abstract

Reaction of ethyleneimine with boron trichloride and tribromide below −20° C, with reactants in ratios 1∶1 and 2∶1, gives labile N-β-halo-genoethyl-substituted halogenoborazenes of the types XCH2CH2NHBX2 and (XCH2CH2NH)2BX (X = Cl, Br). These compounds decomposed spontaneously on coming to room temperature, with the evolution of HX and formation of substances whose compositions are, respectively C2H4NBX2 and C4H9N2BX2. With a 3∶1 ratio of reactants the product is the relatively stable tris(β-halogenoethylamino)borane (XCH2CH2NH)3 B (X = Cl, Br), which loses only one molecule of HX when heated under vacuum.
