Direct conversion of alcohol silyl ethers into the corresponding diphenylmethyl (DPM) ethers can be easily performed by the reaction with diphenylmethyl formate in the presence of a catalytic amount of trimethylsilyl trifluoromethanesulfonate. By the additional use of triethylsilane, tetrahydropyranyl ethers can be also converted into the corresponding DPM ethers.
在催化量的三氟甲磺酸三甲基甲硅烷基酯存在下,通过与甲酸二苯甲酯反应,可以很容易地将醇甲硅烷基醚直接转化为相应的二苯甲基 (DPM) 醚。通过额外使用三乙基硅烷,四氢吡喃基醚也可以转化为相应的 DPM 醚。
