Tunable chemoselectivity (O‐ versus C‐attack) in the rhodium‐catalyzed reactions of allenols with 4‐substituted‐1‐sulfonyl‐1,2,3‐triazoles has been achieved through the replacement of the 4‐aryl substituent by a 4‐acetyl moiety.
在烯丙醇与4-取代1-磺酰基--1,2,3-三唑的铑催化反应中,可调节的化学选择性(O-与C-攻击)可通过用4-取代4-芳基取代基来实现乙酰基部分。
