β-Keto sulfoxides were prepared by the reaction of the esters with the methylsulfinyl carbanion. The nitrosation of the β-keto sulfoxides, RCOCH2SOCH3 (R=C6H5, C6H5CH2CH2, n-C3H7), with sodium nitrite and hydrochloric acid gave the corresponding α-chloro-α-isonitroso ketones, RCOC(=NOH)Cl, in high yields. However, the nitrosation of α-substituted β-keto sulfoxide, RCOCH(R′)SOCH3, in a similar manner
β-酮亚砜是通过酯与甲基亚磺酰基碳负离子反应制备的。β-酮亚砜 RCOCH2SOCH3(R=C6H5、C6H5CH2CH2、n-C3H7)与亚硝酸钠和盐酸的亚硝化反应得到相应的 α-氯-α-异亚硝基酮 RCOC(=NOH)Cl,收率高. 然而,α-取代的 β-酮亚砜 RCOCH(R') SOCH3 以类似的方式亚硝化得到 α-异亚硝基酮,RCOC(=NOH)R'。研究了这些反应的机理。
