[reaction: see text]. Allyl and benzyl 2-lithioaryl ethers, generated by bromine-lithium exchange in THF, undergo a new tandem anion translocation-[1,2]-Wittig rearrangement allowing the isolation of the corresponding benzylic alcohols.
[反应:请参见文字]。在THF中通过
溴-
锂交换生成的烯丙基和苄基2-
硫代芳基醚经过新的串联阴离子易位-[1,2] -Wittig重排,从而可以分离出相应的
苄醇。
