inhibited by sodium hydroxide. Acetic acid, however, removes the first ethyl group rapidly, followed by a slower removal of the second. The protonolysis of the third ethyl group requires elevated temperatures. The unusual reactivity of carboxylic acid toward protonolysis of triethylborane is attributed to the presence of both acidic and basic sites in close proximity. The effect of added reagents is also
三乙基
硼烷在室温下的
水解非常缓慢,不受
盐酸影响,但受
氢氧化钠抑制。但是,
乙酸可快速除去第一个乙基,然后较慢地除去第二个。第三乙基的质子分解需要升高的温度。
羧酸对三乙基
硼烷质子分解的异常反应性归因于紧邻的酸性和碱性位点的存在。还研究了添加试剂的作用。因此,诸如
吡啶之类的碱抑制第一乙基的去除,而羟基溶剂,
水以及强酸和碱阻碍第
二乙基的质子分解。
