The direct α-sulfidation of tertiary amidesusing sulfoxide reagents under electrophilic amide activation conditions is described. Employing convenient and readily available reagents, selective functionalization takes place to generate isolable sulfonium ions en route to α-sulfide amides. Mechanistic studies identified activated sulfoxides as promoters of the desired transformation and enabled the

sulphoxides Ph·[CH2]n·SO·Me (n= 0–4) were compared in pyrolytic and mass spectrometric behaviour. On pyrolysis either β-elimination or rearrangement occurred, but similar effects were not observed in the massspectra. The attempted preparation of one of the sulphoxides actually yielded the next higher homologue by a complex series of reactions.
在热解和质谱分析行为中比较了亚砜Ph·[CH 2 ] n ·SO·Me(n = 0–4)。在热解过程中,发生了β-消除或重排,但在质谱图中未观察到类似的作用。通过一系列复杂的反应,尝试制备一种亚砜实际上产生了下一个更高的同系物。
