Thiazolium carbene-catalyzed reactions of 1,2-diketones and 1,2,3-triketones with enones and ynones have been investigated. The diketones gave α,β-double acylation products via unique Breslow intermediates isolable as acid salts, whereas the triketones formed stable adducts with the NHC instead of the coupling products.
已对噻唑鎓卡宾催化的1,2 - 二酮和1,2,3 - 三酮与烯酮和炔酮的反应进行了研究。二酮通过可作为酸盐分离的独特布雷斯洛中间体生成α,β - 双酰化产物,而三酮与氮杂环卡宾形成稳定的加合物而非偶联产物。
