The disparate reaction pattern allowed the separate activation of non-ylidic S-alkyl and S-aryl bond. Under acidic conditions, sulfonium ylides serve as alkyl cation precursors which facilitate the alkylations. While under alkaline conditions, cleavage of non-ylidic S-aryl bond produces O-arylated compounds efficiently. The robustness of the protocols were established by the excellent compatibility of

金属条件下参与烷基化和芳基化的锍叶立德。不同的反应模式允许单独激活非叶立基S-烷基和S-芳基键。在酸性条件下,锍叶立德用作促进烷基化的烷基阳离子前体。而在碱性条件下,非叶立基 S-芳基键的断裂可有效地产生O-芳基化化合物。协议的稳健性是由包括
碳水化合物在内的各种底物的出色兼容性建立的。
