摘要
以环庚酮及环己(庚)胺为起始原料,经溴代、环化和脱硫等反应,以良好的收率合成了环烷基取代的新型噻唑骨架的氮杂环卡宾催化剂。结果表明:在该催化剂催化下成功地实现了烯烃的自由基氟烷基酰化反应,并以中等收率完成了三种类型的γ-氟烷基取代酮的高效合成。所得化合物通过^(1)H NMR,^(13)C NMR,^(19)F NMR和HR-MS(ESI-TOF)进行表征。
Novel thiazole-based N-heterocyclic carbene(NHC)catalysts with cycloalkyl were synthesized in good yields via bromination,cyclization,desulfurization,etc,using cycloheptanone and cyclo-hexex(-heptyl)amine as the starting material.The radical acylfluoroalkylation of olefins was achieved through the prepared NHC organocatalysis,giving three kinds ofγ-fluoroalkyl ketones with moderate yields.The obtained compounds were characterized by ^(1)H NMR,^(13)C NMR,^(19)F NMR and HR-MS(ESI-TOF).
