Benzylation of alcohols with benzyl (Z)-2,2,2-trifluoro-N-(2-alkynylphenyl)acetimidates 5a-f in the presence of a cationic gold(I) catalyst was investigated. Reagent 5f was the most effective, affording benzyl ethers in good yields. Our results indicate that these gold(I)-activated imidates are effective leaving groups.
研究了在阳离子金(I)催化剂存在下,醇与苄基(Z)-2,2,2,2-三氟-N-(2-炔基苯基)乙亚胺酸酯5a-f的苯甲酸酯化反应。试剂5f是最有效的,以高收率提供了苄基醚。我们的结果表明,这些金(I)活化的酰亚胺是有效的离去基团。
