Benzylidene acetals of 1,2- and 1,3-glycols are easily cleft by diisobutylaluminum hydride in a toluene solution at 0 °C–room temperature to give the corresponding monobenzyl ethers of the glycols. In general the reaction proceeds excellently in regioselective manner depending on the stereochemical environment.
1,2- 和 1,3- 乙二醇的亚苄基缩醛很容易被二异丁基氢化铝在甲苯溶液中在 0 °C - 室温下裂解,得到相应的乙二醇单苄基醚。通常,该反应根据立体化学环境以区域选择性方式出色地进行。
