研究了ω-甲亚砜基苯乙酮阴离子与对硝基苄基衍生物的反应. 它们在室温下经由C-烷基化和消除反应生成ω-(4-硝基苄叉)苯乙酮. 由阴离子对带有弱离去基团的p-硝基苄叉衍生物的C-烷基化是通过亲核重排取代反应的机理进行的.

The anion of w-(methylsulfinyl)acetophenone reacts with 4-O2NC6H4CH2R (R = Cl, Br, iodo, Me3N+ I-) at room temperature via C-alkylation and elimination to give w-(4-nitrobenzylidene)acetophenone. The C-alkylation of the p-nitrobenzyl derivatives with poor leaving groups by anion has been demonstrated to proceed via the SRN1 mechanism.
