    Description / Table of Contents: Bis(dialkylamino) boranes, (R2N)2BH, are easily prepared either by hydrogenation of the corresponding chlorides, (R2N)2BCl, by means of LiH or by transamination of [(CH3)2N]2BH. From the reaction products and two moles of HCl, dialkylammonium chlorides and the easily dimerizing dialkylamino chloroboranes, R2NB(H)Cl, are obtained. These react, in the monomeric form, with further HCl to R2NH · B(H)Cl2. In contrast with the other bis(dialkylamino)-boranes, [(CH3)2N]2BH reacts with HCl without any cleavage of the B-N bond yielding the salt [Cl(H)B(NHMe2)2]Cl.
    Notes: Bis(dialkylamino)-borane, (R2N)2BH, sind durch Hydrierung von Bis(dialkylamino)chloroboranen mit Lithiumhydrid in Äther und durch Umaminierung von Bis(dimethylamino)-boran leicht zugänglich. Bei der Umsetzung der Bis(dialkylamino)-borane mit 2 Mol HCl erhält man Dialkylaminhydrochloride und Dialkylamino-chloro-borane, R2NB(H)Cl, die sich leicht dimerisieren. An die monomeren Verbindungen lagert sich HCl zu R2NH · B(H)Cl2 an. Im Gegensatz zu den anderen Bis(dialkylamino)-boranen reagiert (Me2N)2BH mit HCl ohne Spaltung der B-N-Bindung zu dem Salz [Cl(H)B · (NHMe2)2]Cl.
