Relief of the ring strain of medium-sized rings promotes a regioselective allylic transposition of a C–O bond when catalyzed by rhenium oxide. Through the allylic transposition, eight-membered cyclic silyl ethers undergo ring contraction to the corresponding six-membered siloxacycles.
rh氧化物催化时,中型环的环应力的释放促进了C–O键的区域选择性烯丙基转位。通过烯丙基转座,八元环甲硅烷基醚经历环收缩成相应的六元硅氧烷环。
