An efficient method for the transformation of benzyl alcohols into their methyl or ethyl ethers has been established using 2,4,6-trichloro-1,3,5-triazine (TCT) and dimethyl sulfoxide in methanol or ethanol. This procedure chemoselectively converts benzylic hydroxys into their methyl or ethyl ethers in the presence of aliphatic or phenolic hydroxys.
一种高效的方法已利用2,4,6-三氯-1,3,5-三嗪(TCT)与二甲基亚砜在甲醇或乙醇中的反应,实现了苄醇向其甲基或乙基醚的转化。该方法能在脂肪族或酚羟基存在下,化学选择性地将苄位羟基转化为甲基或乙基醚。
