DIPPnacAlH(2)与DIPPNH_2BH3的反应没有得到预期的去质子化，而是在B位发生了亲核取代反应。对产物DIPPnacnacAl(BH4)(2)进行了分离和结构表征。B位的亲核取代可能在与金属胺基硼烷络合物相关的机械途径中起作用。
Reaction of DIPPnacnacAlH(2) with DIPPNH2BH3 did not give the anticipated deprotonation but nucleophilic substitution at B was observed instead. The product DIPPnacnacAl(BH4)(2) was isolated and structurally characterized. Nucleophilic displacement at B might play a role in mechanistic pathways related to metal amidoborane complexes.
