建立了一种以β-芳甲酰硫代酰胺(KTAs)和丙二腈为合成砌块合成噻唑啉衍生物的新方法.采用廉价的四正丁基碘化胺(TBAI)/叔丁基过氧化氢(TBHP)为催化氧化体系,在三乙胺存在下,室温反应1 h得到一系列4-氨基噻唑啉衍生物.该方法具有操作简便、反应条件温和、反应时间短、后处理简单、环境友好等特点.

Two novel N-heterocyclic carbene-palladium (II) complexes were conveniently synthesized through one-pot reactions of imidazolium salts,palladium chloride and acridine.The new complexes have been fully characterized by 1H NMR,13C NMR,elemental analysis,and X-ray single-crystal diffraction.Moreover,the obtained palladium (II) complexes were the effective catalyst precursors for the Suzuki-Miyaura coupling of aryl as well as benzyl chlorides with arylboronic acids.Under the optimal conditions,all reactions proceeded successfully to give the desired products in good to almost quantitative yields.

Key words: thiazolylidenes, β-ketothioamides, TBAI/TBHP, catalysis
