bismuth(III) halides (BiX3; X=Cl, Br and I) towards a series of alcohols has been investigated. Three different reactions have been studied, namely: halogenation, dehydration and etherification. The behaviour of these bismuth derivatives was found to depend on the nature of the halide bonded to the bismuth atom. Their reactivities can be interpreted on the basis of the Hard and Soft Acids and Bases
研究了卤化铋(III)(BiX 3; X = Cl,Br和I)对一系列醇的反应性。已经研究了三种不同的反应,即:卤化,脱水和醚化。发现这些铋衍生物的行为取决于结合到铋原子上的卤化物的性质。它们的反应性可以根据硬酸和软酸和碱(HSAB)原理进行解释。提出了一种机制,该机制涉及形成醇与Bi(III)的复合物。
