Several amine-cyano(pyrrolyl)boranecomplexes [A · BH(NC4H4)CN] containing a chiral boron atom were prepared from the reactions of sodium cyanohydrodipyrrolylborate-tridioxane1 [NaBH(NC4H4)2CN · 3C4H8O2] with amine hydrochlorides as well as by base exchange from the appropriate 4-cyanopyridine complex [4-CNC5H4N · BH(NC4H4)CN]. Amines with an sp2 N atom give stable complexes of a wide range of basicity
若干胺氰基(吡咯基)硼烷配合物[A·BH(NC 4 H ^ 4)CN]含有手性硼原子被选自钠cyanohydrodipyrrolylborate-tridioxane的反应制备1 [加入NaBH(NC 4 H ^ 4)2 CN·3C 4 H 8 O 2 ]与胺盐酸盐以及通过从适当的4-氰基吡啶络合物[4-CNC 5 H 4 N·BH(NC 4 H 4)CN]进行碱交换。带有sp 2 N原子的胺可提供多种碱度的稳定络合物(p K a= 0.8-9.7),与sp 3杂化N的胺类相反,后者只有更强的碱(p K a 7.3 7.3)才能产生稳定的络合物(主要是仲胺和叔胺)。这些化合物在中性和碱性介质中会发生水解,而在强酸中,它们会通过在吡咯基的α-C原子上质子化产生稳定的硼离子。化合物(-)-(S)-α-苯乙胺-(-)-氰基吡咯烷硼烷和(+)-(R)-α-苯乙胺-(+)-氰基吡咯烷硼烷已制备成纯净
