nes is described and their NMR spectra are interpreted. The reaction of 2-(pyrazol-1′-yl)-1,3,2,-diazaboracyclohexanes with pyrazoles was found to lead to 1/1 molar adducts which exist in equlibrium with the uncomplexed species, whereas B-tetraalkylpyrazaboles are obtained on reaction with (dimethylamino)dialkylboranes. Similar reactions of 2-(pyrazol-l′-yl)-1,3,2-diazaboracyclopentanes with several
描述了几种1,3-二甲基-2-(azol-1'-yl)-1,3,2-二氮杂硼杂环己烷的制备方法,并解释了其NMR光谱。发现2-(吡唑-1'-基)-1,3,2,-二氮杂硼环己烷与吡唑的反应可导致1/1摩尔加合物,与不复杂的物质平衡存在,而B通过与(二甲基氨基)二烷基硼烷反应获得-四烷基吡唑。研究了2-(吡唑-1'-基)-1,3,2-二氮杂硼杂环戊烷与其他几个氮供体分子的类似反应。发现各种物种的化学性质受到1,3,2-二氮杂硼杂环烷基烷环的NBN键角的极大影响。吡唑硼酮与单胺的反应需要非常高的温度,但是这会促进配体的大量重新分布。从该方法不能得到单体的吡唑-1-基硼烷。
