A new, general, one pot method for introducing carbocyclic rings alpha to a nitrile moiety is described. Treatment of readily available arylacetonitriles with potassium bis(trimethylsilyl)amide and subsequent alkylation with α, ω-dibromo or dichloroalkanes in tetrahydrofuran under anhydrous conditions at 0 °C produces cycloalkyl adducts in good yields and short reaction times.
描述了一种新的通用一锅法,用于在腈基前引入碳环。将 readily available 的芳基乙腈与氨基钾双(trimethylsilyl)处理,随后在无水条件下于0 °C的四氢呋喃中与α,ω-二溴或二氯烷烃进行烷基化,可以在短反应时间内以良好的产率生成环烷基附加物。
